Compilation of source emissions data and their use in air quality models
The Multistate Atmospheric Power Production Pollution Study (MAP3S) is addressed to the physical understanding and the mathematical characterization of wet and dry deposition of atmospheric pollutants. The compilation of a source emissions inventory is one of the tasks of the Central Data Coordination project of the MAP3S program. One of the major problems encountered in correlating these data sets is in the area of standardizarion. The use and refinement of emission factor data is an ongoing project. An overall summary of the current inventory data on NO/sub x/, SO/sub x/, CO, hydrocarbons, and particulates is presented. A breakdown of the point source emissions by industrial groupings is tabulated. To allow greater refinement in the treatment of area source data a proposed methodology to disaggregate these emissions to a subcounty level involves the use of the population figures and population centroids available in the MED-X file. Depending on the size of the area to be modeled, an appropriate level of demographic data aggregation can be chosen and population figures and population centroids calculated using the figures for enumeration districts and block groups available in MED-X. The emissions data can then be apportioned to each centroid according to population and again considered as low-level pseudo-point sources. Implementation of this methodology is currently being studied.
