2020 Modeling Platform with model ready and pre-merged emissions, icbc and mcip for running CMAQ

The emissions in the 2020 Modeling Platform are based on the 2020 National Emissions Inventory released in the spring of 2023. The platform was created as part of a project for the Centers for Disease Control and Prevention (CDC) to produce derived estimates of air quality for the year 2020 using the Bayesian Space-time Downscaling Fusion Model (Downscaler) and in support of AirToxScreen for 2020. This platform does not contain projection years. The emissions inputs (model ready and pre-merged) to CMAQ are provided in this data set along with the initial and boundary condition files (icbc) and meteorological inputs (mcip).
