This report describes the Eastern North American Model for Air Pollution (ENAMAP-2), which simulates the long-range transport and deposition of air pollutants across eastern North America. There are two versions of the model-one for sulfur compounds (ENAMAP-2S) and one for nitrogen compounds (ENAMAP-2N). January and August 1977 SO2 and sulfate wet and dry depositions and average ambient concentrations were simulated by ENAMAP-2S and compared to those simulated by an earlier version of the model. In addition, a sensitivity study was conducted to estimate model uncertainties resulting from uncertainties in the values of the model parameters. Finally, January and August NO, NO2, PAN, HNO3, and NO3(-1) wet and dry depositions and average ambient concentrations were simulated.
