Emissions inventories for urban airshed model application in the Philadelphia Aqcr (Air Quality Control Region)

Technical Report · Thu Apr 01 04:00:00 EST 1982

OSTI ID:5745791

This report documents the procedures used to develop emissions input required by the Urban Airshed photochemical oxidant model. Ambient air quality data were gathered as part of another effort during the summer of 1979 in Philadelphia to be used in the model validation effort. For 1979 and the 1987 projection year, ES compiled hour by hour emissions data for a representative weekday in the oxidant season. The pollutants inventoried are five categories of VOC required by the Airshed model, four categories of VOC defined in RAPS, NO, NO2, CO, SO2, and TSP. Point and area sources were considered with the highway vehicle portion of the inventory being subcontracted to DVRPC. County level area source data were allocated to a 502-cell grid system. Projections were made so that ozone air quality in 1987 could be investigated. ES developed annualized EIS/PandR data and data files containing temporal and VOC/NOx profiles in order to generate the data packets required by the Airshed model.
