Abstract
A layman can estimate downwind concentrations of air pollutants from a forest fire if he has such references as the Workbook of Atmospheric Dispersion Estimates.1 He will have to study the references for quite awhile, however, before he feels competent to estimate. The Southern Forest Fire Laboratory is trying to make the layman’s job easier by documenting the calculation procedure for the special case of a prescribed fire acting as a line source. A number of simplifications are possible: one is in estimating insolation.
