PREFACE
A major function of the Continuous Air Monitoring Projects of the
National Air Surveillance Networks since 1962 has been to operate
automatic sampler-analyzer instruments to measure gaseous pollutant
levels in major U.S. cities. This report brings together summaries
of average and maximum monthly pollution levels which have appeared
as portions of previous CAMP publications. The data cover the years
1962-1967 inclusive.
CAMP stations have been in continuous operation since 1962 in
Philadelphia, Pennsylvania; Washington, D. C. ; Chicago, Illinois;
and Cincinnati, Ohio. The station originally placed in New Orleans,
Louisiana in 1962 was moved to St. Louis, Missouri, in 1964. The
station originally placed in San Francisco, California in 1962 was moved
toDenver, Colorado in 1965.
More complete data are available from the National Air Pollution
Control Administration, Division of Air Quality and Emission Data.

DESCRIPTION OF TABLES
Table 1 presents annual averages of carbon monoxide, nitric oxide,
nitrogen dioxide, sulfur dioxide, hydrocarbons, and total oxidants at the
Continuous Air Monitoring Projects (CAMP) stations. The averages
published here include all days containing sufficient data (at least 13
valid hourly averages) to justify calculating a daily average. Some pre-
viously published summaries have included all valid hourly averages
without regard to daily validity; therefore, some values may differ by
a small amount from values appearing elsewhere. The differences are
not important.
An immediate reaction to these averages is to look for possible
trends; however, the variability from year to year is of such a degree
that no significant trends can be verified.
Tables 2 through 37 list monthly averages, and the maximum daily
average, maximum hourly average, and maximum 5-minute reading for
each month, by city. These tables provide some perspective on the
maximum short interval concentrations associated with respresentative
monthly averages, and the seasonal patterns in these maximums. There
must be at least 16 days of valid data to warrant calculating a monthly
average. There are instances •wherein a representative yearly average
cannot be calculated even though more than 50 percent of the daily averages
are valid. This is because pollutant concentrations characteristically
fluctuate with the changing seasons, and the annual average can be unfairly
biased if 3 or 4 months of data are missing during a season when a pollu-
tant characteristically reaches its highest or lowest values.
Maximums occurring on Saturdays and Sundays are so identified.
Intuitively, one would not expect maximum concentrations to occur on
Saturdays and Sundays as frequently as on weekdays because of diminished
industrial activity and traffic peaks on weekends. This is usually the case.
Total oxidant maximums, however, often occur on Saturdays and Sundays
more frequently than the maximums of the other pollutants; the frequencies
are much closer to the one-seventh proportion that would be expected for
each of these days if concentrations varied without respect to the day of
the •week.
-------
The summary of annual averages (Table 1) does not include averages
for total oxidant in 1962 and 1963 because interference in the instrument
from sulfur dioxide, when present in the atmosphere, lowered the oxidant
readings. Prefilters were installed in 1964, and these eliminate the
interference. Data on total oxidants for 1962 and 1963 do appear in the
monthly summary tables, but their value is limited to a relative indication
of seasonal variation. Measurements of t'otal oxidants at the New Orleans
and San Francisco stations -were not affected by this interference as much
as those at the other stations because sulfur dioxide concentrations were
typically quite low at these two stations.
Total oxidant maximums in the 1-hour and 5-minute columns are
selected from the 6-hour interval from 11 a.m. (1100 hours) to 5 p.m.
(1655 hours) to place emphasis on high concentrations of oxidants attribu-
ted to photochemical reactions in the atmosphere. Occasionally, higher
values occur during the night; they are attributed to oxidizing substances
from some unidentified sources, but the principal concern at present is
with the oxidizing substances associated with photochemical reactions
during daylight hours.
More detailed data summaries are available from the National Air
Pollution Control Administration, Ballston Center Tower No. 2, 801
