Abstract |
The Pollution Episodic Model Version 2 (PEM-2) is an urban-scale model designed to predict short term average ground-level concentrations and deposition fluxes of one or two gaseous or particulate pollutants at multiple receptors. The two pollutants may be non-reactive, or chemically-coupled through a first-order chemical transformation. Up to 300 isolated point sources and 50 distributed area sources may be considered in the calculations. Concentration and deposition flux estimates are made using hourly mean meteorological data. Up to a maximum of 24 hourly scenarios of meteorology may be included in an averaging period. The concentration algorithms used in PEM-2 are specially developed to account for the effects of dry deposition, sedimentation, and first-order chemical transformation. The Gaussian plume-type algorithms for point sources are derived from analytical solutions of a gradient-transfer model. The User's Guide lists the concentration algorithms and computational techniques used in the PEM-2 program, and describes the input/output parameters, optional features, capabilities, and limitations of the model. Modifications to the previous version of the model are outlined. The information in the report is directed to the model user and the programmer. |
