Description:

EPA’s National Emission Inventory has been incorporated into the Emission Database for Global Atmospheric Research-Hemispheric Transport of Air Pollutants (EDGAR-HTAP) version 2. This work involves the creation of a detailed mapping of EPA Source Classification Codes (SCC) to the International Nomenclature for Reporting System (NFR). We will report on the methods and details of this database linkage including the spatial gridding, cross-referencing, temporal allocation, and chemical speciation for the 2008 NEI. The mapping of SCC codes to the NFR system allows for comparison of USA emission inventories with other national inventories on a consistent basis. The chemical speciation of the inventory into 25 NMVOC aggregation groups allows for consistent comparison of the VOCs independent of chemical mechanisms employed in chemical transport models. We summarize the emission estimates for 2006, 2008, and 2010 and provide a useful reference for linking USA inventories to Global inventories for use in regional and global chemical transport models.

Purpose/Objective:

The National Exposure Research Laboratory (NERL) Atmospheric Modeling and Analysis Division (AMAD) conducts research in support of EPA mission to protect human health and the environment. AMAD research program is engaged in developing and evaluating predictive atmospheric models on all spatial and temporal scales for forecasting the air quality and for assessing changes in air quality and air pollutant exposures, as affected by changes in ecosystem management and regulatory decisions. AMAD is responsible for providing a sound scientific and technical basis for regulatory policies based on air quality models to improve ambient air quality. The models developed by AMAD are being used by EPA, NOAA, and the air pollution community in understanding and forecasting not only the magnitude of the air pollution problem, but also in developing emission control policies and regulations for air quality improvements.
