The Pollution Episodic Model Version 2 (PEM-2) is an urban-scale model capable of predicting short-term ground-level concentrations and deposition fluxes of one or two gaseous or particulate reactive pollutants at multiple receptors. The report describes an evaluation of the PEM-2 using 1982 Philadelphia Aerosol Field Study (PAFS) data for 29 days. The model's performance is judged by comparing the calculated 12-hour average concentrations with the corresponding observed values for four pollutant species, namely, SO/sub 2/, particulate sulfate, and fine and coarse particulate total mass. The diurnal variations of hourly SO/sub 2/ concentrations at each of the six PAFS stations are also compared. Hourly meteorological and emission data are used as inputs to the model. The emission inventory consists of 300 point sources and 289 area sources in the Philadelphia urban area.
