2022v2 Emissions Modeling Platform Technical Support Document
This TSD describes how emission inventories were prepared for air quality modeling by the U.S. Environmental Protection Agency (EPA) to represent the year 2022 in Version 2 of the 2022 emissions modeling platform. This document focuses on the emissions modeling data and techniques including the emission inventories, the ancillary data files, and the approaches used to transform inventories for use in air quality modeling. The differences between the data and emissions modeling techniques in this version and Version 1 of the 2022 emissions modeling platform are discussed.
