Seasonal variability of sulfur wet deposition predictions have been assessed for a six-year period (1976-1981). From a 1980 SO2 emissions data base and a 1976-1981 meteorological data base, the Advanced Statistical Trajectory Regional Air Pollution (ASTRAP) model produced 30 seasonal and annual sulfur wet deposition patterns and source-receptor matrices for North America. In addition, patterns of the coefficients of variation were also produced. The annual wet deposition patterns were very similar with the maximum amounts predicted across eastern Ohio, western Pennsylvania and northern West Virginia. Variability of the seasonal patterns was more pronounced, especially for winter. The coefficients of variation were the smallest where the maximum depositions were predicted and greater in remote regions.
