The Incorporation of the US National Emission Inventory into Version 2 of the Hemispheric Transport of Air Pollutants Inventory
EPA’s 2008 National Emission Inventory has been incorporated into version 2 of the Hemispheric Transport of Air Pollutants Inventory. This work involves the creation of a detailed mapping of EPA Source Classification Codes (SCC) to the International Nomenclature for Reporting System (NFR). The mapping of SCC codes to the NFR system allows for comparison of USA emission inventories with other national inventories on a consistent basis. We summarize the emission estimates for 2008 and 2010 and provide a useful reference for linking USA inventories to Global inventories for use in regional and global chemical transport models.
