A study was carried out to apply and test the Eastern North American Model of Air Pollution (ENAMAP-1), a regional trajectory-type model that is an adapted version of the European Model of Air Pollution (EURMAP-1) developed by SRI International (SRI) for the Federal Republic of Germany. The ENAMAP-1 model calculations were based on all available wind and precipitation data and on specialized emission data prepared for the Sulfate Regional Experiment (SURE) program. The ENAMAP-1 model has been tested to determine the variability of the model's seasonal calculations caused by year-to-year changes in wind and precipitation patterns. Sulfur emission data for 1977 were used with meteorological data and annual sulfur concentrations, depositions, and regional exchanges. The calculated results appeared to be in reasonably good agreement with the available air quality measurements. The effects of yearly variations in the transport winds were most noticeable in the monthly SO=4 concentration patterns and in the SO=4 wet-deposition fields; the latter also showed strong sensitivity to yearly variations in precipitation.
