A long-range transport model of SO2 and sulfate for twenty-four-hour concentration distributions was refined and applied to calculate distribution patterns of concentration and deposition of SO2 and sulfate over the area between 35N and 45N and between 75W and 95W for January 25 and July 11, 1976. The calculated concentrations and the observed concentrations were compared. A climatological model of long-range transport of SO2 and sulfate was also refined to calculate average monthly distributions of SO2 and sulfate concentrations as well as the acidity of precipitation due to sulfate and the budget of sulfur over eastern North America. The model has been applied for the months of January 1977 and March 1979 over the area between 35N and 55N and between 62W and 95W. The results are described. Empirical studies of precipitation chemistry data were conducted and indicate that inclusion of NOx/NO3 in the long-range transport model is important to improve the predictability of precipitation acidity.
