| Abstract |
The STEM-II model was applied to a case study of the acid deposition upwind and downwind of Philadelphia, Pennsylvania. The model has the Atkinson-Lloyd kinetics mechanism for gas phase chemistry and an aqueous phase mechanism for 22 species. The model results indicate that the major trends in the data are correctly simulated. Time histories at particular grid locations are consistent with the known meteorological conditions. |
