National Mobile Inventory Model (NMIM)
Abstract
The National Mobile Inventory Model (NMIM) is a consolidated emissions modeling system for EPA’s MOBILE6 and NONROAD models. It was developed to produce, in a consistent and automated way, national, county-level mobile source emissions inventories for the National Emissions Inventory (NEI) and for EPA rule making. NMIM comprises a Java framework, graphical and command line user interfaces, the MOBILE6 and NONROAD models, the NMIM county database (NCD), and postprocessing and aggregation capabilities. Note: MOBILE6, used in NMIM, has been replaced by MOVES as EPA’s official model for estimating emissions from cars, trucks, and motorcycles. Thus, NMIM cannot be used for official modeling of these emissions.
