The National Air Data Branch of EPA has the responsibility for developing an accurate emissions inventory for all designated pollutants for the entire United States. The emissions inventory data must be in a format suitable for use as input to existing computer programs for displaying air quality, or for evaluating State Implementation Plans. Area source emission data present problems. Usually, the smallest geographic unit for which accurate primary data are available is the county. These data must be disaggregated and appropriately allocated to smaller areas to provide an adequately detailed input. The Computer Assisted Area Source Emissions gridding programs with associated subroutines and off-line procedures provide an objective method for allocating county-level data to grid squares selected on the basis of demographic features and sized to give appropriate detail for input to air quality modeling programs.
