ABSTRACT
An Atlas of air quality and deposition data has been compiled to make air pollution data and
information more accessible to biologists and ecologists working in western forests. Data from the
1985 National Acid Precipitation Assessment Program Emission Inventory are used to characterize
emissions of sulphur dioxide and nitrogen oxides across the West Maps illustrating location, type,
and magnitude of major point source emissions together with pie charts of the percent contribution
by source category are presented alphabetically by state. Data from the Environmental Protection
Agency databases AIRS and SAROAD are used to characterize ambient levels of sulphur dioxide
and ozone for three averaging periods, viz., annual, May through October or growing season, and
monthly. Data for 20 sulphur dioxide and 70 ozone sites in or near western forests are presented
by state. Biographic information together with standard summary statistics are given for each site.
Summary statistics for sulphur dioxide include frequency of occurrence of hourly sulphur dioxide
concentrations between 9 intervals, viz., 0-10, 10-20, 20-30, 30-40, 40-50, 50-60, 60-70, 70-80,
& 80 ppb. Summary statistics for ozone include percentile distributions, mean and standard
deviation, cumulative indices SUM06 and SUM08, and a description of the diurnal patterns
experienced at each site. Data for 32 wet deposition sites in the National Atmospheric Deposition
Program/National Trends Network (NADP/NTN) are presented by state for the three averaging
periods. Biographic information together with several summary statistics are given for each site.
Summary statistics include percentile distributions for weekly pH, and weekly concentrations (mg/L)
for sulphate, nitrate, and ammonium. Annual and seasonal deposition estimates for volume
weighted average concentrations and deposition (kg/ha) are also given.

1. INTRODUCTION
Subsequent to their discovery and documentation
in Scandinavia and north-eastern America, acid
deposition and gaseous pollution episodes have
been reported in several locations in the western
United States. Southern and central California
have received particular attention especially with
respect to episodes of ozone (O3), sulphur dioxide
(SO;), and nitrogen oxides (NOX) (Miller et at
1986; Jacob et al. 1987; Bytnerowicz et aL 1987),
deposition loadings of acidic ions (Leonard and
Goldman 1981; Liljestrand and Morgan 1982;
Stohlgren and Parsons 1987), and haze and cloud
episodes (Macias and Zwicker 1981; Munger et aL
1990). Observations of acidic precipitation and
of sensitive high elevation watersheds showing
signs of acidification have been reported in
Colorado (Nagamoto et al. 1983; Turk and Adams
1983; Harte et al. 1985; Reddy and Claassen 1985;
Turk and Campbell 1987). Add deposition and
haze episodes in the Pacific Northwest (McBean
and Nikleva 1986; Edmonds and Basabe 1989)
and Central States (Dawson 1978; Flocchini et aL
1981a, 1981b; Macias and Zwicker 1981; Linak
and Peterson 1983; Messer 1983; Thomas and
Buseck 1983) are becoming more frequently
documented.
There is little doubt that air pollution is
capable of harming forests, either by direct effects,
such as visible injury (e.g., Miller et al. 1963;
Skelly et al. 1987), or by indirect effects, such as
impacts of acid deposition on soils (e.g., Tabatabai
1985; Reuss and Johnson 1986), predisposing the
ecosystem to attacks by pests (e.g., Cobb et al.
1968; Stark et aL 1968), or community changes
(e.g., Miller 1973). Thresholds at which
pollutants cause damage to vegetation are widely
debated especially for natural, multi-species
systems. Furthermore, regional assessments of
forest condition are inhibited by complex
interactions between species, pollutants, and
environmental conditions.
The role played by air pollution on forest
growth and vigor has been investigated in the
United States by local studies as well as by
national programs such as the National Acid
Precipitation Assessment Program (NAPAP),
Integrated Forest Studies (IPS), and Response of
Plants to Integrated Stress (ROPIS). With the
exception of southern California, the western
United States is generally believed to be without
an air pollution problem, especially in remote,
forested areas. This conclusion is usually based
on direct comparisons of ozone concentrations
and annual wet depositions of sulphate in rain
and snow between sites in the eastern and western
United States. Little consideration is given to
differences in pollutant sensitivity between eastern
and western ecosystems nor to differences in the
nature, magnitude, and seasonally of
environmental stress experienced by eastern versus
western .forests. To further enhance the
inapplicability of such direct comparisons, large
areas of the West are without monitoring data,
especially high elevation forests.
Population densities across the West are
typically a fraction of those of the eastern United
States. However, in areas with high population
densities, such as southern California, ozone levels
are comparable to or exceed those for similar
areas in the east Western forests surrounding
densely populated valleys experience adverse
effects such as foliar injury and reductions in
growth (e.g., Miller et aL 1963; Miller et aL 1989;
Pedersen 1989; Peterson et aL 1989). Southern
and central California provide a window into the
future of forests surrounding major western cites
such as Seattle, Salt Lake City, Phoenix,
Albuquerque, and Denver.
The western United States has a legacy of
beautiful forests and mountains. Increasing
reports of atmospheric fallout and pollution
episodes in the West together with ecological
damage to European and eastern American
forests, provide sufficient reason for westerners to
be concerned about the future of their heritage.
The Western Conifers Research Cooperative was
charged by NAPAP to investigate forest condition
across the West Pan of the program involved
accumulation of information on air quality and
deposition in or near western forests. The data
were obtained from a variety of sources such as
the Environmental Protection Agency's (EPA)
National Emissions Data System (NEDS) and
Aerometric Information Retrieval System (AIRS),
National Atmospheric Deposition Program and
individual research projects. The results of the
Western Conifers Atmospheric Project have been
and are being published in the peer reviewed
literature (Behm 1989; Muir and Behm 1989;
Behm et al. 1990; Warren et al. 1990, Behm
1990b) and in peer reviewed government reports
-------
(Behm lS»90a; Reams et al. 1990; Sisterton et al.
1990). These papers describe regional
characteristics of ambient concentrations and
deposition of air pollutants in or near western
forests, together with detailed analyses of ozone
and wet deposition under western conditions.
It is not the purpose of this Atlas to
provide detailed spatial or within site analyses.
These have been performed elsewhere and the
interested user is referred to the general literature
listed above.
Objectives and Aims
General or regional descriptions rarely provide
scientists with the kinds of air quality and
deposition information needed to link air
pollution exposure with vegetation effects and
responses. The main objective of this Atlas is to
summarize readily available air quality and
deposition data for the western United States
using a variety of summary parameters as
surrogates for air pollution exposure. Specifically,
the purposes of the Atlas are:
• provide a comprehensive description of
emissions of sulphur and nitrogen oxides across
the West; of ambient concentrations of sulphur
dioxide and ozone in or near western forests; of
the ionic chemistry of rain and snow in or near
western forests; and of deposition loadings
during rain and snow events to western forests.
• develop a convenient reference on air quality
and deposition that can be used to guide
western forest research scientists on the
potential for their system being exposed to air
pollutants.
• provide air quality and deposition data
summaries in a flexible format that allows
integration with biological effects information.
• present actual data used to create the published
regional summaries.
The Atlas consists of (1) a brief
description of the forests of the West; (2) a
section on emissions of sulphur dioxide and
nitrogen oxides across the West; (3) a section on
ambient concentrations of sulphur dioxide and
ozone, together with concentrations and
depositions of ionic species in rain and snow.
Methods used to generate the summaries are
discussed in each subsection.
2. WESTERN FORESTS
The eleven western states occupy about 40% of
the land area of the conterminous United States.
About one third of the West is forested (Figure
2.1). Coverage by state ranges from 11% in
Nevada to 55% in Washington. Approximately
61% of western forests are federally owned.
The West is characterized by extreme
relief with massive north-south mountain ranges
separated by basins, valleys, and plateaus. The
large area together with diversity of topography,
climate, and soils lead to a corresponding diversity
of species and forest types. With the exception
of the Pacific Northwest, extensive forests only
occur in the mountains. Natural disturbances are
important determinants of forest structure and
species composition in the West (Oliver 1981).
At any given time, a large proportion of western
forests are in a serial stage following fire, insect
or disease outbreaks, or wind-throws. Fire is the
most important natural disturbance over much of
the West
Conifers dominate western forests,
presumably because of better adaption to the
summer drought-winter precipitation climate that
prevails over much of the West Ponderosa pine
(pinus ponderosa), lodgepole pine (Pinus
contorts), and Douglas-fir (Pseudotsuga menziesii)
are most common (Figure 2.1). Only 14% of
forest land in the West is classified with a non-
conifer type. Furthermore, hardwoods are usually
only important in specialized situations such as
riparian habitats, early successional stages, or
certain xeric, low elevation habitats. The only
major hardwood with distribution throughout the
West is quaking aspen (Populus tremuloides). A
detailed discussion of the distribution of forest
species throughout the West is available in
Whitney (1985) and Olson (1990).

3. EMISSIONS
Point sources of sulphur and nitrogen dioxide are
scattered .across the eleven western states (Figures
3.1 and 3.2). In 1985, the estimated total sulphur
dioxide emissions for the West was 2.15 Tg
(1 Tg = 1 million metric tons), 10% of the
national estimate, and 3.01 Tg for nitrogen oxides
or 16% of the national estimate (Placet and
Streets 1987). State totals for 1985 ranged
between 0.04 and 0.59 Tg for sulphur dioxide and
between 0.08 and 1.11 Tg for nitrogen oxides
(Table 3.1). County estimates of total sulphur
and total nitrogen dioxide emissions (point and
area sources) are presented in Figures 33 and 3.4.
The interested reader is referred to Placet and
Streets (1987), Roth et al. (1985), Hidy and
Young (1986), and Bahm (1990b) for more
information on emissions of pollutants across the
western United States.
Sources of Data
Data on the locations of point sources and on
estimated annual emissions of sulphur and
nitrogen dioxide were obtained from National
Acid Precipitation Assessment Program's 1985
Emission Inventory, considered by many to be the
most current, complete, and accurate large-scale
inventory available for the West (NEDS 1985;
Sellars and Morris 1989). Annual emission
estimates for 1987/1988 were obtained from State
Departments of Air and Environmental Quality.
Emissions data are not measured values.
Instead, the emission factor is multiplied by the
activity level of the source for a given time period
to yield an estimate of emissions from that source.
Consequently, emission inventories possess varying
degrees of uncertainty. Langstaff and Wagner
(1986) estimated the uncertainties associated with
the 1980 NAPAP Emissions Inventory.
Uncertainty values of 1% (based on a 90%
confidence interval) were estimated for total
national annual emissions of sulphur dioxide and
nitrogen oxides. Uncertainty levels increased to
6% and 4%, respectively, for state-level total
emissions of sulphur dioxide and nitrogen oxides.
At the county level, uncertainty levels of annual
emissions of sulphur dioxide and nitrogen oxides
were estimated at 16%. The uncertainty estimates
for national annual emissions may be lower than
expected since errors associated with systematic
bias and with the use of mean parameters for
estimating emissions estimates were not included
in the uncertainty analysis (Placet and Streets
1987).
A panel of 13 inventory experts reviewed
the 1985 NAPAP Emissions Inventory (Sellars
and Norris 1989). Although uncertainty estimates
were not reported by Sellars and Norris, the panel
concluded that the quality of the 1985 industrial
process point source emission estimates was high;
that the national emission estimates for specific
categories appear to be more credible than
estimates available in earlier inventories; and that
area source emissions estimates were at best
'planning estimates' and for some categories,
'guesstimates'.
Atlas Format
Maps illustrating the location, type, and
magnitude of major point sources (annual
estimated emissions i 100 Mg, where
1 Mg = 1 metric ton) of sulphur and nitrogen
dioxide, together with pie charts illustrating the
percent contribution by source category to annual
emissions (point source only) are presented
alphabetically by state for 1985 (Appendix 1).
The maps and pie charts were generated directly
from the emissions database (NEDS 1985).
Summary Statistics
Magnitude of annual estimated emissions from
point sources during 1985 is represented as one of
three categories, 10* - 103 Mg, 103 - 10* Mg, or
10* -105 Mg. Industries are separated into seven
categories, viz., metal industry, electric generation,
petroleum industry, chemical processes, industrial
fuel use, mineral products, and other. Activities
such as wood products, food/agriculture, leather
products, textile manufacturing, evaporation, and
waste disposal were designated "other*.
The percent contribution of specific
source types to total point source emissions at
state level during 1985 is presented as pie charts.
Total emissions for the state during 1985 are
available in Table 3.1.

a Total U.S. emissions for 1980 presented here are about 0.9 Tg lower than those in the NAPAP

combustion of nonpurchased fuels in the industrial sector.
b Totals presented for 1985 are the sum of the 1985 power plant emissions (calculated using the
same methodology as Knudson, 1986) and the 1984 values from Knudson (1986) for sulphur
dioxide, and 1984 estimates for vehicular emissions for nitrogen oxides. The estimates do not

4. AIR QUALITY AND DEPOSITION
This section presents information on sulphur
dioxide, ozone, and precipitation chemistry.
Information on the deposition of ions during rain
and snow events is also presented. Data
summaries for nitrogen dioxide are not included
since nitrogen oxides are readily oxidized and have
short residence times in the atmosphere. The
effects of nitrogen oxides on plants are not
frequently studied and, for example, are not even
considered by Skelly et al. (1987).
Sources of Data
Data describing ambient concentrations of sulphur
dioxide, ozone, and the chemistry of precipitation
across the West were assembled from public data
bases and short-term monitoring projects, some of
which were funded by Western Conifers Research
Cooperative. The time period under
consideration, January 1980 through December
1989, was chosen to limit uncertainties that may
arise from non-standard calibration techniques
used for ozone monitors prior to EPA
standardization in 1979. A detailed description of
monitoring techniques is available in Lefohn and
Benkovitz (1990).
Hourly concentrations of ambient sulphur
dioxide and ozone are monitored by the State
Departments of Environmental Health or Air
Quality. The data from these sites are fed into
the EPA Aerometric Information Retrieval
System (AIRS; previously SAROAD) as part of
attainment analyses. In addition to compulsory
monitoring sites, several states and research
organizations also collect air pollution data as
part of special projects funded at state level.
These data are archived and are often available to
the public. During the study period, '254 sulphur
dioxide and 309 ozone monitoring sites were
operational across the eleven western states,
however, not all of these sites were active during
the entire summary period.
Weekly composite precipitation samples
are collected throughout the West as part of the
National Atmospheric Deposition
Program/National Trends Network (NADP/NTN).
The weekly, seasonal or annual chemical data are
available to the public through the NADP/NTN
Coordination Office at Colorado State University.
Monthly volume weighted averages can also be
obtained from the NADP/NTN Coordination
Office and from the Acid Deposition System Data
Base (ADS) at Battelle Pacific Northwest
Laboratories. Seventy-seven NADP/NTN wet
deposition sites were operational in the eleven
western states during the study period, however,
not all of these sites were active during the entire
summary period.
Siting Criterion
The sulphur dioxide, ozone, and wet deposition
sites are usually not located within or near
coniferous forests. A siting criterion of 20 km
from the boundaries of coniferous forests was
applied to select sites summarized in this Atlas.
These sites were identified electronically in a
Geographic Information System using latitude,
longitude, and 1:2,500,000 ecoregion maps
(Omerick and Gallant 1986; Omerick 1987).
Although ecoregion maps are compiled using
many different factors besides vegetation type, the
ecoregions identified as typically covered with
coniferous forests correlate well with those
depicted on the 1:3,168,000 Natural Vegetation
Map (Kuchler 1975) and 1:7,500,000 Major Forest
Types Map (National Atlas of the United States
Map 1970). Surprisingly no recent map showing
the forests of the West could be found with a
scale greater than 1:2^00,000. This is the
smallest scale required to identify individual air
quality monitoring sites, especially in southern
California.
A total of 20 sulphur dioxide, 70 ozone,
and 32 wet deposition sites were located within
20 km of forest ecoregion boundaries. Large
areas are without air quality and deposition
monitoring sites especially in Idaho, Montana,
Wyoming, and Utah. Furthermore, air quality
data from sites in complex terrain typical of the
West are often not representative of regional
pollution characteristics. This follows from the
influences of topography and meteorology on the
dilution and transport of air pollutants. For
example, topography can restrict dispersion of
pollutants from a basin and higher pollution
levels may be measured at sites beneath inversion
height than in forests at elevations above
inversion height. Intrusions of polluted air up
canyons and passes during valley and anabatic
10
-------
winds cause spatial heterogeneity in air quality
characteristics over short distances. A more
detailed discussion of air pollution meteorology in
complex terrain and western forests is offered by
Oke (1987) and Behm (19905).
Data Quality
Data reported in the Sulphur Dioxide and Wet
Deposition sections originated from the same data
bases, viz., SAROAD and NADP/NTN
respectively. The data within these sections are
directly comparable since they were subjected to
the same collection and measurement criteria, and
data quality routines. The accuracy and precision
of sulphur dioxide data are reported by AIRS
(formally SAROAD), a detailed description of
which is given in Lefohn and Benkovitz (1990).
NADP/NTN operates using several Quality
Assurance Programs that address site selection,
sample collection techniques, field and laboratory
measurements. Accuracy and precision of
precipitation chemistry and wet deposition data
are described by NADP/NTN in the Annual and
Quality Assurance Reports available from the
NADP/NTN Coordination Office at Colorado
State University.
The data reported in the Ozone section
originated from four sources, viz., AIRS, the
National Park Service (NFS), Washington State
Department of Ecology, and Washington
University. Although a formal quality assurance
plan is not available for NFS ozone data, the data
from the NPS Network are included in the AIRS
data base. Since NPS data have to conform with
AIRS standards to be included in the data base,
we consider NPS ozone data to be comparable
with AIRS data in the context of this Atlas. The
collection and measurement procedures used by
Washington State Department of Ecology and
Washington University follow Environmental
Protection Agency guidelines (Washington State
Depanment of Ecology Air Programs 1989;
Edmonds et aL 1989). We consider the data from
these two sources to be comparable with AIRS
and NPS data in the context of this Atlas. The
accuracy and precision of ozone data reported by
AIRS and NPS is described in detail by Lefohn
and Benkovitz (1990). The accuracy and precision
of ozone data collected by Washington State
Depanment of Ecology and Washington
University is reported by Washington State
Department of Ecology Air Programs (1989) and
Edmonds et al. (1989) respectively.
Data of poor quality can be generated
when an instrument does not operate correctly.
Data on precipitation chemistry and wet
deposition are carefully screened for data quality
issues by NADP/NTN (National Atmospheric
Deposition Program 1989). Ozone and sulphur
dioxide data are screened by AIRS (formally
SAROAD) as described in von Lehmden and
Nelson (1977) and Puzak and McElroy (1987).
Data presented in the Atlas were not screened
further unless large deviations from expected
values were found. In these cases, the data were
set to missing.
Summary statistics presented in the Atlas
usually do not estimate missing data, although it
is recognized that missing data can lead to large
underestimations of cumulative indices such as
SUM06 or SUM08 for ozone and wet deposition
of ions. Sulphur dioxide and ozone monitors
usually undergo a span check once a day that
results in a missing value every 24 hours. Span
checks occur at the same time, frequently late at
night Ozone summary statistics reported in the
Atlas for sites with low ozone values at night are
rarely influenced by these missing data.
Unfortunately, ozone statistics for rural and
remote sites, especially those at high elevation,
may be influenced by these missing data since
ozone levels can range from 20 to above 60 ppb
at night (e,g., Bohm et aL 1990). Sulphur dioxide
summary statistics may also be influenced by
missing data from span checks, especially if the
monitor is close to a point source that emits
effluent below the temperature inversion.
Missing data are also generated when an
instrument fails to operate. In this case, blocks of
missing data usually occur. The missing hours are
often uniformly distributed, but data on air
pollution episodes may not be collected if the
instrument is non-operational Consequently,
estimates of data capture are included in the
summary tables to guide the user as to the
representativeness of the data summaries.
A detailed description of summary
parameters is given for each pollutant in its
relevant section.

Air Pollution Statistics and Biological Significance
A preliminary step in understanding ecological
consequences of pollutant exposure is knowledge
of plant physiological processes that influence
pollutant uptake. These processes affect the
sequence from external pollutant exposure to
biologically significant pollutant dose, and control
a multitude of temporary and permanent
physiological responses. Intrinsic differences
between species need to be understood to develop
exposure-response functions for important species
within western forest ecosystems. Variable
environmental conditions for each individual and
through the canopy of a single individual
influence exposure-response functions within
genetically determined boundaries. Long term
consequences of pollutant exposure are difficult to
understand because of scale problems related to
the long life spans of trees.
Unfortunately, our present state of
knowledge does not allow consistent
quantification of links between air pollution
exposure and plant or ecosystem response.
Established relationships between various
exposure characteristics and plant response pined
from laboratory experiments usually on annual
plants imply that both the magnitude of the
pollutant concentration and the length of
exposure are important However, for all
practical purposes, very little is known about the
effect of both single and multiple pollutant
exposures on natural and managed forest
ecosystem:; under field conditions where additional
environmental stresses influence the physiology of
organisms exposed.
Over the years much effort has been
placed in developing biologically meaningful
indices for pollutant exposure (e.g., Lefohn and
Benedict 1982; Heck et aL 1984; Lefohn et aL
1986; Lefohn and Runeckles 1987; Krupa and
Kickert 1S>87; Hogsett et aL 1988; Lee et aL 1988;
Tingey et aL 1989). A review of the literature
implies that a single exposure index for a
particular pollutant will probably not apply to all
plant species, field conditions, and exposure levels.
Our approach is to present several summary
statistics, thereby allowing the user to decide
which method yields an appropriate surrogate for
pollutant uptake for the plant species of interest
to that user. We wish to stress that summary
statistics in this Atlas are not linked to biological
effects until biologists apply the air quality data to
their research or apply the information based on
their research.
The choice of summary statistics used to
characterize each pollutant was based on known
or suspected mechanisms of damage to forest
trees. For convenience, common summary
statistics are also included. Descriptions and
possible interpretations of the summary statistics
are presented by pollutant in subsequent sections.
Since ozone is the only regionally dispersed
pollutant known to injure trees and because
ozone damage to forests in southern and central
California is well documented, more emphasis is
placed on summarizing ozone concentrations than
on summarizing sulphur dioxide and precipitation
chemistry.
In the real world, plants are exposed to a
melange of stresses all at once. Co-occurrence of
exposure to several pollutants can, under
laboratory conditions, lead to exacerbated effects
in certain plant species (e.g., Olszyk et aL 1989).
Many of these pollutants, such as sulphur dioxide
and ozone, do not often co-occur under natural
conditions (e.g., Lefohn et aL 1987). Thus we did
not investigate hourly co-occurrence of pollutants,
however, the summary tables for different
pollutants are arranged so that some inference
can be obtained on co-occurrence or sequential
exposure of forests to different pollutants.

4A. SULPHUR DIOXIDE
Sources of Data
Direct foliar injury to plants can occur after 1
hour exposures to sulphur dioxide concentrations
of 500 ppb (e.g., Heck and Brandt 1977;
McLaughlin 1981). Sulphur dioxide damage need
not be visible. There is some evidence that
annual average concentrations as low as 10 to 20
ppb, together with occasional peaks of between
40 and '• ppb can reduce tree growth (Last and
Rennk 1982).
Sulphur dioxide injury to forest trees is
usually restricted to areas where undiluted plumes
frequently come into contact with the ground.
Forests located in areas with poor atmospheric
ventilation are most susceptible to damage from
sulphur dioxide. Thus, emissions of sulphur
dioxide within valleys usually cause more injury to
adjacent forests than do emissions from sources
located in well-ventilated terrain (Skelly et al.
1987).
Regional levels of sulphur dioxide are low
across the West, although pockets of high
concentrations do occur. Sites recording high
sulphur dioxide levels are usually located dose to
large point sources. Hourly concentrations in
excess of 80 ppb occur relatively frequently at
monitoring sites in southern Arizona, Idaho, and
Montana (Beam 1989). During periods of poor
atmospheric ventilation, hourly sulphur dioxide
levels in the San Joaquin Valley, California,
averaged around 40 ppb with maximum values of
up to 60 ppb (Jacob et al. 1987). Sulphur dioxide
measurements at Tanque Verde near Tucson,
Arizona, were typically below the detection limit
of the instrument, although hourly concentrations
as high as 30 ppb were recorded on occasion
di .; both summer and winter months (Linak
a /eterson 1983).
Sulphur dioxide abatement strategies have
resulted in large reductions in emissions at many
point sources across the West, especially in the
smelter industry. Current levels of sulphur
dioxide, where measured, are probably lower than
those referred to above. However, there are very
few sulphur dioxide monitors in or near forested
areas in the West and additional pockets of high
sulphur dioxide concentrations, thus far
unmeasured, may occur near many point sources
across the area.
Hourly concentrations of ambient sulphur dioxide
were obtained from the Environmental Protection
Agency (SAROAD, currently AIRS) and were
analyzed by Dr. Allen Lefohn of A.S. & L.
Associates, Helena, Montana. The study period
spans 01 January, 1980 through 31 December,
1988. All sites followed EPA calibration and
monitoring guidelines, although not all sites
operated for the entire study period.
Atlas Format
Data tables are presented alphabetically by site

site provides BIOGRAPHIC INFORMATION for
that site that is available in SAROAD. The site
name and state are clearly marked at the top of

site together with locations of other sulphur
dioxide sites within 20 km of forests in that state
is presented. The site under discussion is
demarcated with a star, remaining sites are
represented by a small circle. Geographic data
such as latitude, longitude, and elevation of the
site in meters, are presented. Information on
landuse around the site, on population of the
nearest city and of the region as a whole (1980
Census), is given. The period for which data were
available is indicated. The source of the data,

purpose of this page is to provide the user with
spatial data and useful information about the site.
The second page presents BASIC
STATISTICS for the site. Again the site name is
clearly marked at the top of the page. Tables of
basic statistics are given for three averaging
periods, viz., BY YEAR, BY CROWING
SEASON, and BY MONTH. Derivations of
statistics are explained below in the "Summary
Statistics* section. "0* indicates no occurrence, *-
• indicates missing data, and "0.1* refers to the
range of percent occurrences from 0.01 to 0.09.
The purpose of these tables is to provide the user
with some standard summary statistics describing
the frequency of occurrence of sulphur dioxide
concentrations.

4B. OZONE
Atlas Format
Ozone is formed by the photolysis of nitrogen
oxides in the presence of non-methane
hydrocarbons. Although nitrogen dioxide is the
primary precursor of ozone, nitric oxide formed
during the photolysis reaction reacts rapidly with
ozone to form nitrogen dioxide and oxygen.
Thus, nitric oxide and ozone do not co-exist in
the atmosphere and the relationship between
formation and scavenging processes determine
ambient ozone concentrations (Finlayson-Pitts and
Pitts 1986).
Ozone is the only regionally dispersed
pollutant known to injure foliage and lead to tree
mortality at ambient levels (Miller 1973;
Woodman 1987). Ponderosa and Jeffrey! pine
trees in the mixed conifer forests of southern
Sierra Nevada and San Bernardino Mountains in
California exhibit, in many cases, severe foliar
injury. Changes in ecosystem composition and
growth rates have occurred (e.g., Miller 1973;
Peterson et aL 1989). Visible damage attributable
to ozone has not been recorded in other forests
of the West
High ozone concentrations do occur
downwind of most large urban complexes such as
Seattle, WA; Salt Lake City, UT, Phoenix, AZ,
and Denver, CO (Behm 1989). The interested
reader is referred to Lefohn and Pinkerton (1988);
Fehsenfeld et aL (1983); Lefohn et al. (1990);
Basabe et al. (1989); Edmonds and Basabe (1989);
Baton (1990b).
Sources of Data
Hourly concentrations of ambient ozone were
obtained from the EPA AIRS data base, from the
National Park Service (NPS), Washington
Department of Ecology, and Washington
University (through the Electric Power Research
Institute and Edmonds et aL (1989)). To limit
uncertainties associated with nonstandard
calibration techniques prior to EPA
standardization in 1979, the study period spans 01
January, 1980 through 31 December, 1989. All
sites followed EPA calibration and monitoring
guidelines, although not all sites operated for the
entire study period.
Data tables are presented alphabetically by site
and state (Appendix 3). The first page for each
site provides BIOGRAPHIC INFORMATION for
that site that is available in AIRS. The site name
and state are clearly marked at the top of the
page. A map displaying the location of the site
together with locations of other ozone sites within
20 km of forests in that state is presented. The
site under discussion is demarcated with a star,
remaining sites are represented by a small circle.
Geographic data such as latitude, longitude,
elevation of the site in meters, and elevation of
the valley or basin floor in meters, are presented.
Information on landuse around the site, on
population of the nearest city and of the region as
a whole (as defined in AIRS), is given. The
period for which data were available is indicated.
The source of the data, together with AIRS codes
for AIRS sites, is given. The purpose of this page
is to provide the user with spatial data and useful
auxiliary information about the site.

ozone concentrations and frequency of occurrence
of certain ozone concentrations.
The third page provides information on
DIURNAL PATTERNS IN HOURLY OZONE
CONCENTRATIONS, or on the dynamics of
ozone exposure. The site name is clearly marked

occurrence of patterns (Behm et aL 1990) are
given for three averaging periods, viz., BY YEAR,
BY GROWING SEASON, and BY MONTH.
Derivations of the information are explained
below in "Summary Statistics* section. "0"
indicates no occurrence and "-" indicates missing
data. The purpose of these tables is to provide
detailed information on the diurnal and seasonal
characteristics'of the dynamics of ozone exposure
at the site.

-------
The fourth page displays the shape of
DOMINANT DIURNAL PATTERNS IN HOURLY
OZONE CONCENTRATIONS (MAY . OCT)
experienced during the growing season. Again,
the site name is clearly marked at the top of the
page. Derivation of the information is explained
below in 'Summary Statistics* section. The
purpose of these graphs is to provide a quick-look
capability for both magnitude of ozone
experienced at a site as well as dynamics of
exposure.
Summary Statistics
Adverse ozone effects can occur at concentrations
above 60 ppb (Pell 1974), however effects
generally develop after short exposures to
concentrations greater than 80 ppb (Taylor 1973).
The response of vegetation to ozone is influenced
by diurnal and seasonal patterns in exposure
(Hogsett et aL 1985), as well as by the magnitude
of ozone concentrations and length of exposure
(e.g., Tingey and Taylor 1982; Guderian 1985).
Summary statistics should be sensitive to these
characteristics of ozone exposure.
The ozone data are summarized for three
averaging periods, (1) January • December or BY
YEAR; (2) May - October or BY GROWING
SEASON; and (3) Months composited over years
or BY MONTH. These averaging periods provide
the user with a choice of resolution and allow
integration of ozone summary information with
biological data at a variety of levels. Some sites
were not operational for the entire averaging
period. Under these conditions, operational
months are included in parentheses behind the
summary period heading. Percent data capture
and percent valid days are given for each summary
period. Hourly data are considered valid if they
are not missing. A day is considered valid if 75%
of hours between 09:00 and 21:00 have valid
ozone data (Federal Register 1979). For the BY
YEAR averaging period,
% data capture - (# valid hours / # hours in a year) * 100.
% valid da}* - (* valid days / * days in a year) *100.
Usually a year has 8760 hours and 365 days,
although leap years have 8784 hours and 366 days.
For the BY GROWING SEASON averaging
period,
% data capture - (# valid hours / 4416) • 100.
% valid days = (* valid days / 184) • 100.
The period May through October has 4416 hours
and 184 days. If a site was not operational during
the entire averaging period, data capture is still
calculated as described above, but operational
months are listed in parentheses behind the
summary period heading. For the BY MONTH
averaging period,
% data capture - (* valid hours / (# years with valid data for
that month • * hours in that month) ) • 100.
% valid days - (# valid days / (« yean with valid data for
that month • * days in that month) ) • 100.
Months with 31 days have 744 hours, months with
30 days have 720 hours, and February has 28 days
and 672 hours during normal years and 29 days
and 696 hours during leap years.
BASIC STATISTICS are given for each
averaging period, Lex, BY YEAR, BY GROWING
SEASON, and BY MONTH. Missing data were
usually neither estimated nor included in the
calculations, consequently data captures are
presented for each summary period. A data
capture of 50% indicates that half of the available
data were valid and were used to generate the
summary statistics. Summary statistics associated
with low data captures are not as representative
of the averaging period as are statistics associated
with high data captures. The user of this Atlas is
encouraged to compare BY YEAR, BY
GROWING SEASON, and BY MONTH data
captures to obtain a feel for the distribution of
missing data for a particular site. The user has
the option to regard or disregard summary
information for a given summary period based on
a level of uncertainty acceptable to that user.
Data captures t 75% are often considered
representative of the population (e.g., California
Air Resources Board 1987). The following
statistics are tabulated:
1.5*. 10*. 25*. 50*, 75*. 90*. and 95*
percentiles for the hourly data over the
averaging period. If the desired percentile fell
between two numbers, the arithmetic mean of
the numbers was used as the percentile.
16
-------
2. Arithmetic mean and standard deviation (ppb)
for hourly data over the averaging period. The
data for several sites are not continuous but
are rather at discrete intervals of 5 or 10 ppb;
for completeness, the mean and standard
deviation are reported for these sites.
3. Cumulative indices S06 and SOS (ppm hr):
S06 - I [O3] 11000 where [O3] * 60 ppb.
SOS - Z [Oj] / 1000 where [O3] * 80 ppb.
Cumulative indices are sensitive to missing
data. If data captures are less than 100%,
cumulative indices may under-estimate reality
depending on the distribution of missing hours.
For the averaging period MONTH, the
cumulative indices are normalized as follows:
S06n - S06 • (# houn in that month) / (# valid noun).
S08n « SOS • (# houn in that month) / (* valid boun).
This approach assumes that the missing hours
are uniformly distributed across the averaging
period. In the event of no instrument failure,
the missing hours are not uniformly distributed
since span checks usually occur every 24 hours
at the same time. Normalized cumulative
indices for sites with data captures *96% (i.e.,
missing data are only due to span checks) are
thus probably over-estimates of reality. In the
event of instrument failure, frequencies of
occurrence of missing hours are often
uniformly distributed and the normalized
cumulative indices are probably good
surrogates of reality. However, there is no
means of determining if an air pollution
episode occurred during the period of
instrument failure. If such an episode did
occur, the normalized cumulative indices would
under-estimate reality. If lower ozone levels
occurred during the period of instrument
failure than during the remainder of the
averaging period, the converse is true.
Cumulative indices for GROWING SEASON
were not normalized. We feel that a generic
normalization routine applied to indices of
long averaging periods for all sites in the
analysis increases uncertainty to the point that
the index is of little value. The data presented
for 806 and SOS under BY GROWING
SEASON provide the user with a lower bound.
We consider the uncertainty associated with
this estimate to be proportional to the data
capture reported for the summary period.
Users who wish to estimate total cumulative
indices for a particular site or time period are
encouraged to pursue the missing data issue
from the original data.
4. Percent of valid hours during the averaging
period with ozone concentrations greater than
or equal to 60,80,100, and 120 ppb. In some
cases the cumulative indices are greater than 0
although the percent valid hours for 60 and 80
ppb are reported as "0*; the percent valid hours
were actually between 0.0 and 0.5% and were
thus rounded to "0". Missing data were neither
estimated nor included in the calculation of the
percentages.
5. The number of days with ozone concentrations
1120 ppb were determined from all the data
in the averaging period, and not only from
valid days.
Summary information presented in the
BASIC STATISTICS section provides biologists
with insights on the magnitude of ozone
concentrations and frequencies of exposure to
certain concentrations. However, the response of
vegetation to ozone also appears to be influenced
by diurnal and seasonal patterns in exposure
(Hogsett et al. 1985,1988). Thus, information on
DIURNAL PATTERNS IN HOURLY OZONE
CONCENTRATIONS is given for each averaging
period, Le., BY YEAR, BY GROWING
SEASON, and BY MONTH. Seventeen diurnal
patterns in hourly ozone concentrations can be
identified using data from western sites (Figure
4B.1; Bohm et al. 1990). The patterns are labeled
following a letter-number combination describing
the shape of the curve (A - curve with very little
diurnal variation in hourly ozone concentrations;
E - curve with marked diurnal variations in hourly
ozone concentrations) and the magnitude of the
daily mean (1 • small daily mean; 5 - large daily
mean). Each day with 23 or 24 valid hourly
ozone concentrations can be classified against
these 17 patterns using a discriminant analysis and
a prior probability of 0.4. The interested reader
17
-------
is referred to Behm et al. (1990) for a detailed
description of the analysis.
The percent occurrence of the 17 patterns
is presented for averaging periods BY YEAR, BY
GROWING SEASON, and BY MONTH.
Percent unclassified days, or days with diurnal
patterns in hourly ozone concentrations not
closely associated with the 17 classification
patterns (prior probability < 0.4 in discriminant
analysis), is also given for each summary period.
Detailed information on the characteristics of
ozone oiposure is available from these tables.
Firstly, siites far removed from pollution source
areas experience patterns with little fluctuation in
hourly ozone concentrations whereas sites close to
pollution source areas characteristically exhibit
bell-shaped curves of ozone concentrations with
maxima around the middle of the day. Thus, the
frequency of occurrence tables can be used to
identify subtle changes in ozone exposure at a site
prior to there being noticeable changes in the
basic statistics. Secondly, the tables can be used
in a modelling framework. Detailed information
on ozone: exposure can be recreated in the
modelling environment by simply using a 24 X 17
matrix describing the seventeen classification
patterns and a frequency of occurrence matrix for
the site and period of interest Thirdly, responses
of vegetatiion to ozone can be easily investigated
at a monthly level, allowing integration of ozone
exposure dynamics with phonological and other
biological or environmental information.
A visual interpretation of the most
common diurnal patterns in hourly ozone
concentrations during the growing season is
presented in the DOMINANT DIURNAL
PATTERNS IN HOURLY OZONE
CONCENTRATIONS (MAY - OCT) section. The
graphs illustrate the average shape of the curve
together with one standard deviation. Curves
accounting for up to 75% of days during the
growing season are shown with the most common
curves at the base of the page. An idea of the
dynamics of ozone exposure is obtained with one
glance. Sites with very little fluctuation in ozone
concentrations, such as Olympic National Park,
require only two patterns to describe 75% of
growing season days. Sites with widely fluctuating
ozone exposures, such as San Bernardino, require
five patterns to describe 75% of growing season
days. Actual percent occurrences are available
from B. BY GROWING SEASON (All Years)
in the DIURNAL PATTERNS IN HOURLY
OZONE CONCENTRATIONS section of the
previous page.

4C. WET DEPOSITION FROM RAIN AND SNOW
Sources of Data
The chemistry of rain and snow and deposition of
acidic ions are monitored near several forested
areas across the West as pan of the National
Atmospheric Deposition Program/National Trends
Network ((NADP/NTN). Volume weighted
average pH varies from 4.7 in southern Arizona
and New Mexico, 5.0 in southern California,
western Washington, and the Southwest including
parts of Colorado, to 53 in eastern Oregon,
Idaho, and Montana (Figure 4Clb). Mean
weekly pH values range from 4.6 to 5.4. Volume
weighted sulphate concentrations (as SO/-) are
generally less than 1 mg/L although mean weekly
concentrations range from 0.5 to 15 mg/L.
Annual sulphate deposition ranges from 1 to
8 kg/ha (Figure 4Clc). Volume weighted nitrate
concentrations (as NO/) are generally less than
1 mg/L although mean weekly concentrations
range from 0.2 to 4.1 mg/L. Annual nitrate
deposition ranges from 1 to 5 kg/ha (Figure
4Cle). Higher concentrations of sulphate and
nitrate occur at sites close to point sources or
large urban settlements (Bohm 1989). Temporal
patterns in deposition are related to seasonal
patterns in precipitation. In general, most
deposition to forested areas in the West occurs
during the winter in the form of snow.
The ionic concentrations and depositions
of precipitation in the West are 15-25% of
eastern values. Depositions of sulphate and
nitrate at high elevations in the West are largely
unknown and may be larger than at low elevations
where the sites are located, since high elevations
usually receive more precipitation than low
elevation sites.
The interested reader is referred to
Dawson (1978), Leonard and Goldman (1981),
Liljestrand and Morgan (1982), Nagamoto et aL
(1983), Harte et al. (1985), Vong et al. (1985),
Galbraith (1986), Hidy and Young (1986), Popp
and Long (1986), Sharpless (1986), Stohlgren and
Parsons (1987), B*hm (1989), Vong (1990) and to
the Annual Reports of NADP/NTN for more
detailed information on acid deposition in the
United States (e.g., National Atmospheric
Deposition Program 1989).
Chemistry and deposition estimates were obtained
from the NADP/NTN Coordination Office at
Colorado State University (National Atmospheric
Deposition Program (IR-7)/National Trends
Network 1990). Deposition estimates do not
cany the same level of confidence as do the
chemical concentrations, since precipitation
volume data are not subjected to the same
rigorous quality assurance tests as precipitation
chemistry data. Deposition values may also
underestimate actual loadings because they are
not adjusted for the percentage of the summary
period for which precipitation amounts were not
available from the rain gauge or sampler. It
should also be mentioned that there are various
problems with sample integrity when using weekly
sampling periods (e.g., Galloway and Likens
1976). Hydrogen ion and ammonium values may
be underestimated due to changes in chemistry
between the end of the event and analysis of the
sample.
Atlas Format
Data tables are presented alphabetically by site
and state (Appendix 4). The first page for each
site provides BIOGRAPHIC INFORMATION for
that site that is available in Robertson and
Wojtiechowski (1986) and National Atmospheric
Deposition Program (1990). The site name and
state are clearly marked at the top of the page.
A map displaying the location of the site together
with locations of other NADP/NTN sites within
20 km of forests in that state is presented. The
site under discussion is demarcated with a star,
remaining sites are represented by a small circle.
Geographic data such as latitude, longitude, and
elevation of the site in meters are presented.
Information on landuse around the site and the
period for which data were available is given.
The source of the data, together with NADP/NTN
identification code, is indicated. The purpose of
this page is to provide the user with spatial data
and useful auxiliary information about the site.

STATISTICS for the site. Again the site name is
clearly marked at the top of the page. The first
table presents percentiles for weekly
concentrations (mg/L) for each year together with

-------
total precipitation measured during that year.
The second table presents volume weighted
averages (mg/L) and deposition estimates (kg/ha)
for each year and for winter (December through
February) and summer (June through August)
summary periods within that year. Data for pH,
sulphate, nitrate, and ammonium are given in
both tables. Derivations of statistics are explained
below in 'Summary Statistics' section. V
indicates no occurrence and '-' indicates missing
data. The purpose of these tables is to provide
the user with some standard summary statistics
describing precipitation chemistry and deposition
during summer, winter, and over the year as a
whole. Similar information for chloride, calcium,
potassium, magnesium, aluminium, and sodium is
available from the NADP/NTN Coordination
Office at Colorado State University. The
NADP/NTN summaries present additional
information that may be of use to the interested
reader.
Summary Statistics
Samples are considered valid for precipitation
chemistry if all of the following criteria are
satisfied (National Atmospheric Deposition
Program 1989):
1. NADP/NTN criteria for site location, sample
collection and handling, and measurement
protocols are satisfied.
2. The sampling interval is 6-8 days.
3. There is a rain gauge depth or sample volume
reported for the sample.
4. The sample consists of Vetonly" deposition,
i.e., it was not exposed to dry deposition during
the sampling interval.
5. A complete set of chemical measurements is
reported for the sample.
6. The sample is not contaminated
Calculations of ion concentration and deposition
statistics are limited to samples that meet the
above criteria. Four completeness criteria form
the basis for the decision to include the data from
a site in the seasonal and annual summary tables
(National Atmospheric Deposition Program 1989):
1. There must be valid samples for at least 75%
of the summary period.
2. For at least 90% of the summary period, there
must be precipitation amounts (including zero
amounts) either from the rain gauge or from
the sample volume.
3. There must be valid samples for at least 75%
of the total precipitation amount reported for
the summary period.
4. For the entire summary period, the total
precipitation as measured from the sample
volume must be at least 75% of the total
precipitation measured by the rain gauge for
all valid samples where both values are
available.
It is important to recognize that if all the criteria
were satisfied at the lower limit of acceptability,
the summary could still account for less than 75%
of the actual precipitation at a site. This could
occur because the 90% precipitation coverage
criterion is based on time and there may be no
record of the amount of precipitation missed
during the unsampled 10% of the period. Where
the precipitation coverage is 100% however, these
criteria ensure that at least 75% of the
precipitation is represented by valid samples
(National Atmospheric Deposition Program 1989).
The interested reader is referred to the
NADP/NTN Coordination Office at Colorado
State University for more information on data
analysis and interpretation.
Only data for sites and years included in
NADP/NTN Annual Summaries are presented in
this Atlas. The following BASIC STATISTICS
are given for each averaging period:
1. 25*, 50*. 75"1, and 90* percentiles together
with the maximum value for weekly data over
the averaging period. Missing data were
neither estimated nor included in the
calculation of the percentiles. If the desired
percentile fell between two numbers, the
arithmetic average was used as the percentile.
21
-------
2. Volume weighted averages for the averaging
period:
X = (z q Pi) I (r P|)
where c, is the concentration (mg/L) for the
ionic species of interest for the P* week and P/
is the precipitation amount for the r* week.
The quantity of precipitation measured by the
rain gauge is usually greater than that captured
in the sampler bucket NADP/NTN considers
the rain gauge measurement to be the best
estimate of precipitation amount, thus rain
gauge rather than sample volume amounts are
used when calculating volume weighted
averages. It is assumed that the chemistry of
the sample, determined from water collected
in the sample bucket, represents the chemistry
for the entire precipitation event
3. Deposition is calculated from the product of
the volume weighted mean concentration and
the total measured precipitation for the
averaging period. Deposition values were not
adjusted for the percentage of the summary
period for which precipitation amounts were
not available from the rain gauge or the
sampler. Measured deposition values may
underestimate actual wet deposition.

5. SUMMARY AND CONCLUSIONS
6. ACKNOWLEDGEMENTS
An Atlas of air quality and deposition has been
compiled! to make air pollution data and
information more accessible to biologists and
ecologists working in western forests. Hie
information is presented in an easy-to-
comprehend format that gives both geographic
and summary data on emissions of sulphur and
nitrogen dioxides, on ambient concentrations of
sulphur dioxide, ozone, and precipitation
chemistry, and on wet deposition of acidic ions at
sites located within 20 km of forest ecoregions
within the West The Atlas also directs users to
the original sources of the data.
The Atlas should be used as a 'quick
look* reference. It is inevitable that as more
atmospheric and biological data become available
and as our knowledge of atmosphere-forest
interactions increases, both the data bases and
analytical approaches presented in this document
will become outdated. A shortcoming of this
Atlas and numeric analysis of large data sets in
general, is treatment of missing values.
Additional research is required to better
characterize the distributions of missing data and
their influence on the accuracy and precision of
reported estimates.
Scientists addressing specific questions on
the response of forests to air pollutants are
encouraged to monitor air pollutants in the
forests of interest For example, most of the
sulphur dioxide and ozone sites used in this Atlas
were not located in forests. Very little is known
about extrapolating air pollution information from
valleys and non-forested areas to forests and
within forests, especially when the forests occur in
complex terrain.
It is important to note that the data
presented in this Atlas merely characterize the
chemical nature of air that may be in contact with
forests close to the monitoring sites and not the
uptake of pollutants by the forest ecosystem. We
reiterate a statement made previously in the
document, "We wish to stress that summary
statistics in this Atlas are not linked to biological
effects until biologists apply the air quality data to
their research or apply the information based on
their research.*
This Atlas would never have materialized without
support and contributions from many people and
institutions, especially NADP/NTN. The original
idea for a data Atlas, and the format of this
document was derived after numerous interactions
with NADP/NTN personnel in various
Subcommittees. Special thanks to the personnel
of AIRS, NEDS, University of Washington, EPRI,
NFS, and State Departments of Air Quality for
their time and effort in preparing the emissions
and ozone data, and to Allen Lefohn for
analyzing the sulphur dioxide data. We would
also like to thank our reviewers for taking the
time to carefully review such a cumbersome
document Their comments provided us with
much food-for-thought and served to produce a
more comprehensible document
