Fic. 135.—Selected percentile curves relating SO: concentrations to wind direction at TAMStations 5-8
of these ranges. Thus, if the wind directions are listed
for every ten degrees, the percentile values will be
repeated as often as necessary.
The order of the variables in the columns should
be arranged so that the last column represents the
variable which influences the SOz concentrations the
least and the first column the most. Further, wind
speed and temperature should be presented in de-
scending order since lowest values of each correspond
to highest SO2 concentration. (Table 62 is a sam-
ple of an intermediate provisional table where the temperature is shown in increasing order. In the final
tables temperatures will appear in decreasing order.)
Ideally, the tabular arrangement should show a
steady increase in values of SOQz2 concentration as one
reads down from the top of the table.
