Abstract
The long-term EURMAP-1 model, a trajectory-type regional air pollution model extensively evaluated and applied in Europe in conjunction with studies of interregional sulfur transport and deposition, was adapted, tested, and applied to eastern North America. The adapted version, ENAMAP-1, was used to calculate monthly, seasonal, and annual distributions of sulfur dioxide and sulfate (SO2 and SO4(-2)) concentrations and wet and dry depositions over the eastern United States, as well as over the southern portions of the Canadian provinces of Quebec and Ontario. This geographical area was partitioned into 13 different regions and interregional sulfur exchanges calculated. Model calculations were based on emission data that included both the specialized data prepared for the Sulfate Regional Experiment (SURE) and the U.S. Environmental Protection Agency's National Emissions Data System (NEDS). Model results using emissions and meteorological data for the year 1977 are presented. Results include tables showing the calculated interregional exchanges of sulfur deposition between 13 regions of eastern North America. Comparisons were made between calculated and measured SO2 and SO4(-2) concentrations. Calculated and measured values show reasonable agreement and indicate that improvements in the calculated values may be achieved by refinements in the modeling of mixing heights and stability. Results are also shown for an application of the model using projected 1985 emissions in conjunction with meteorological data for 1977.
