2005 Version 4 Air Emissions Modeling Platforms
The 2005v4 emissions modeling platforms were based on versions of the 2005 National Emissions Inventory (NEI). The primary use of the 2005v4.1 platform was for the proposed Mercury and Air Toxics Standards. The primary use of the 2005v4.2 platform was for the Cross-state Air Pollution Rule. The primary use of the 2005v4.3 platform was for the final Mercury and Air Toxics Standards. The 2005v4 emissions modeling platforms each include information needed to support the development of emissions inputs for air quality modeling, including the inventories, ancillary data, and scripts required to process the emissions.
