PREFACE
One of the Continuous Air Monitoring Projects of the National Air Surveillance Net-
works is to routinely operate continuous monitoring stations in six major cities. The data
tabulations in this report consist of hourly average concentrations of six gaseous pollutants
(carbon monoxide, nitric oxide, nitrogendioxide, sulfur dioxide, total hydrocarbons, and
. .
total oxidants),' cmd 2-hour measurements otsoiling index levels in Chicago during 1968.
-. . . .
A brief summary of monthly means and maximums and graphs of seasonal diurnal patterns of
gaseous pollutants at the Chicago station are included. Annual frequency distributions of
the data pertaining to gases and soiling index are presented for all six CAMP stations.
Summaries of 1968 data for Chicago, Cincinnati, Philadelphia, St. louis, and
Washington, D. C. are available from the National Air Pollution Control Administration.
Similar data summaries have been publ ished, along with various analyses and interpretative
material, for previous years' operations.

DENVER SEASONAL DIURNAL PATTERNS
Figures 1 through 6 are graphs showing the seasonal diurnal patterns for carbon monoxide,
. . .
nitric oxide, nitrogen dioxide, sulfur dioxide, total hydrocarbons and total oxidants, respec-
tively. Each figure contains four curves, one representing each season, as follows: long-
dashed I ine for summer, short-dashed I ine for autumn, mixed-dashed I ine for winter, and
solid line for spring.
Each curve represents a composite of the approximately 90 daily patterns in each season
plotted by computer using 15-minute averages derived from the basic 5-minute measurements.
Dotted I ines indicate portions of the curve for which insufficient data are available to pro-
vide a valid seasonal average.
The seasons are defined as follows: Winter consists of December, 1967, and January
and February, 1968; spring consists of March, April, May; summer consists of June, July,
and August; and autumn consists of September, October and November, 1968.
It should be noted that CAMP stations operate on a Standard Time basis. Consequently,
during the seasons of Daylight Savings Time, 1-hour shifts may be noted in diurnal patterns
of certain pollutants because of a shift in the patterns of human activity that generates these
pollutants.

GASEOUS POLLUTANT
DATA TABLES

-------
GASEOUS POLLUTANT DATA TABLES
Data tables 3-1 through 3-72 present hourly average concentrations by month for the
gaseous pollutants. Values in these tables are the arithmetic means of the 5-minute values
in the clock hour indicated. An hourly average is not calculated if fewer than seven 5-
minute values during the hour were valid. Similarly, if a calendar day had fewer than 13
val id data hours, it ii considered an invalid data day, and the entire row of averages for
the day is deleted. The reason for this procedure, which results in the loss of a few valid
hourly averages, is that the data that are lost are usually concentrated at the beginning or
end of the day. Since the pollutant concentrations show considerable diurnal variati on, the
inclusion of such data would introduce a definite bias into the monthly mean concentrations.
The first summary line (titled MEAN) at the bottom of the tables contains the arithmetic
means of the hourly averages, and hence represents the pattern of diurnal variation for the
month. Again by the same val idity criterion, this average is not calculated unless 16 or
more hourly averages are present. The second and third summary lines are the number of and
maximum of the hourly averages in the column.
The first summary column (titled DAI L Y MEAN) at the right of the tables is the arithmetic
mean* of the 13 or more hourly averages comprising the row, and the second is the number
of such vali~ hourly averages. The third summary column, however, is not the maximum
hourly average for the day, but the maximum 5-minute value included in the hours of valid
data during the day.
Four summary figures appear in the lower right corner. The upper left is the monthly
average, an arithmetic mean, and appears only if 16 or more days were valid. The center
number is the total number of valid hours included in.the table, which offers s.ome basis for
iudgi~g the representativeness of the monthly average. The lower left summary number is
the maximum daily average from the column above.. The lower right number is the maximum
5-minute value from the column above.
* The summary calculations are performed before the hourly averages are rounded.

SOILING INDEX DATA TABLES
Tables 4-1 .through 4-12 present soiling index values at the station by month. Each value
was obtained from a 2-hour integrated sample beginning at the time indicated in the column
heading. A missing value indicates that the sample was not taken or was inval id because
of instrument malfunction.
The first summary line (titled MONTHLY MEAN) represents the arithmetic mean of the
2-hour average values in the column, and is calculated only if 16 or more days are represented.
The first summary column (titled DAILY MEAN) gives the arithmetic mean of the 2-hour values
for the day; if fewer than seven such values are present, the daily mean is not calculated,
and the data are not included in the summaries; however, the component 2-hour values for
the day are not deleted from the table as is done with the data on gaseous pollutants.
The other summary columns and rows are the number of and maximum of the respective
2-hour values. Four summary figures appear in the lower right corner; the mean and maximum
values for the month are the upper left and lower right figures, respectively, while the center
figure is the total number of values. The lower left summary number is the maximum dai Iy
average from the column above.
