rates of dispersion and, consequently, the concentra-

tions observed downwind. The relations between the
meteorological variables and pollutant concentrations
are complex. Various techniques have been used for
depicting these relationships, such as multiple regres-

sion analysis or diffusion equations such as the Sutton
or Gaussian forms.

DESCRIPTION OF THE TABULATION PREDICTION TECHNIQUE

One way of demonstrating the relation between me-

teorological variables and pollutants is by arranging

combinations of relevant meteorological variables in

an ordered sequence and presenting the associated
probability distribution for each entry as shown in

Table 62. This procedure is referred to as the “Tabulation Prediction Technique” or the “Look-up Tech-

nique” and is based on hourly readings. For each com-

bination of meteorological variables the minimum

value, the 10, 25, 50, 75, 90, 95, 98, 99 percentiles, and

maximum value of SQ. concentrations are shown

Also presented are the mterquartile ranges, i.e., the
difference in SQ. concentration between the 75th and
25th percentiles, and that of the 95th and 75th percentiles. The number of cases observed for each combination of meteorological variables is shown in the
last column. To arrange combinations of meteorologi-

cal variables into an ordered sequence, each of the
selected variables must first be divided into appropri-

ate bands. For example, wind direction is grouped into >
three class intervals, time of day also into three, wind
speed into five, and so forth. A number is assigned to

each class interval of each variable. Thus any com-

bination of, let us say, five meteorological variables
corresponds to a five-digit number. If letters are assigned to each class of each variable, then any com-

bination would correspond to a five letter word. Since

the combinations of meteorological variables are ordered, it is possible to look up any combination just
as one would look up a namein a telephone book or a

word in a dictionary to obtain the probability distri-
