χi = the
sector average concentration value for the ith sector
|
fij
|
= the
frequency of occurrence for the jth wind direction in the ith
sector
|
|
ε(θ)
|
= the
error term - a criterion of ε(θ) < 2 percent is used to check
for convergence of the sector average calculation
|
|
χ(θij)
|
= the
concentration value, based on the numerical integration algorithm using
Equation (1-58) for the jth wind direction in the ith
sector
|
|
θij
|
= the
jth wind direction in the ith sector, j = 1 and N correspond
to the two boundaries of the sector.
|
The application of Equation (2-6a) to calculate the sector average
concentration from area sources is an iterative process. Calculations using the ISC Short Term
algorithm (Equation (1-58)) are initially made for three wind directions,
corresponding to the two boundaries of the sector and the centerline
direction. The algorithm then calculates
the concentration for wind directions midway between the three directions, for
a total of five directions, and calculates the error term. If the error is less than 2 percent, then the
concentration based on five directions is used to represent the sector average,
otherwise, additional wind directions are selected midway between each of the
five directions and the process continued.
This process continues until the convergence criteria, described below,
are satisfied.
