2021 Emissions Modeling Platform
The 2021 Emissions Modeling Platform is based on the 2020 National Emissions Inventory released in the spring of 2023 with some updates to better represent 2021. It was created as part of a product for the Centers for Disease Control and Prevention (CDC) to produce derived estimates of air quality for 2021 using the Bayesian Space-time Downscaling Fusion Model (Downscaler) and in support of AirToxScreen for 2021. The modeling platform contains emissions inventories for 2021, spatial surrogates, temporal profiles, and other ancillary files. This platform does not contain projection years.
