Calculation of σZ and H for an observed vertical profile of concentration

Abstract

In extracting Gaussian plume parameters from transverse profiles of concentration measured in model or full-scale tests of dispersion from an elevated source, a common practice is to employ a statistical best-fit procedure in conjunction with the general equation. This involves 1) a calculation of x by Equation 1 for each data point (y,z) using known parameter Q and combinations of assumed parameters sigma/sub y/, sigma/sub z/, u and H; 2) a comparison of calculated and observed values of x; and 3) minimization of the discrepancy for the complete data set.
