Sulfur Deposition Modeling in Support of the U.S./Canadian Memorandum of Intent on Acid Rain

摘要

At the request of the U.S./Canadian Work Group 2 of the Acid Rain Memorandum of Intent, the Eastern North American Model of Air Pollution (ENAMAP-1) was applied to two months of 1978 to simulate the monthly wet and dry depositions and monthly average ambient concentrations of SO2 and sulfate across eastern North America. Using these model results, unit emission (1.0 Tg S/yr) transfer matrices were generated and a model performance study was performed. In addition, a model sensitivity study was conducted to examine the consequences of model input parameter uncertainties.
