Gaussian plume model predictions of dispersion and ground-level SO2 concentrations were compared to field measurements downwind from the Dickerson, Maryland power plant. The main objective of the work was the evaluation of empirical methods for predicting dispersion in the Gaussian model. Brookhaven dispersion predictions, chosen by a simple algorithm requiring wind speed and temperature gradient information, provided the best results. The geometric mean of the ratio of predicted-to-measured concentration was 1.1 and 85% of the predictions were within a factor of 2 of the measured concentrations when Brookhaven dispersion parameters were used. Dispersion estimates given by Turner, the Tennessee Valley Authority, and the Atomic Energy Commission were at significant variance with the measurements. The effects of plume trapping by an elevated stable layer were included in the analysis. They resulted in significant improvement between observed and calculated concentrations when Brookhaven coefficients were used.
