Description:
Conventional preparation of emission inventories for air quality modeling is typically an extended process using computer routines to reformat, quality check, chemically speciate, and temporally and spatially allocate data. rocessing of emission inventories for regional modeling requires very large data bases and often requires days or weeks of calendar time to prepare the data for specific cases (scenarios) and geographic coverages, and many hours of mainframe computer CPU time. n order to address these problems, an emission processing system is being modified to be an integral part of initial operating version (IOV) of the models-3 System, the object-oriented distributed computing and analysis framework for the Environmental Protection Agency's (EPA) next generation of air quality models. he emission processor will use the most recent software and hardware computing techniques, including visualization, to provide user-specified gridded emission data to the chemistry and transport model (CTM) portion of Models-3 and allow analysis of the effects of different emission scenarios, including projections. uture needs include development of an advanced system with a completely new object-oriented approach for emission processing.
