Abstract - To produce a quick estimate of the maximum ground-level air concentrations and deposition that can be expected for a given release amount at downwind distances after travel times of one to five days after release. The procedure used is a result of analytical and experimental studies and is summarized in a simple nomogram giving the normalized concentration as a function of travel time for a release within the atmospheric boundary layer and for a release above the boundary layer.
