To analyze the impact of ISCST3 estimates of using the sampled meteorological data, we made model runs using five area sources and two point sources. The sources varied in size and particle size distribution. Each source was run with 5 years of meteorological data for four stations: Lake Charles, LA; Pittsburgh, PA; Salem, OR, and Tucson, AZ. The sites were selected to provide a diversity of climatological regimes. A polar grid of receptors along 16 evenly spaced radials at distances ranging from the edge of the source to several kilometers was used. We compared the results of various combinations of sampling rates with the results from using the full meteorological database.
