CMAQ Inputs and Test Case Data
Benchmark Test Case Downloads
Input and benchmark comparison data to test the build of both the base and the coupled models are available from the CMAS Center Data Warehouse Google Drive. The coupled model data are also posted on EPA's anonymous FTP server. The base model benchmark data set is a 14 day CMAQ simulation (July 1 -14, 2016) over the Southeast U.S. (80 row x 100 col) using a 12km grid size. An annual set of model inputs for 2016 for the continental U.S. (CONUS) are also available to download.

The National Emissions Inventory (NEI) Modeling Platforms
Fire Emissions
Fire emissions require fire location, burned areas, and detailed fuel load information. Examples of where to find these types of datasets are proved below. All of these information sources can be used to estimate fire emissions. An example of a tool that can be used to generate fire emissions is the US Forest Service BlueSky modeling framework. BlueSky modularly links a variety of independent models of fire information, fuel loading, fire consumption, fire emissions, and smoke dispersion. SmartFire Version 2 is one component of the BlueSky modeling framework used to reconcile fire information from multiple sources. Using these tools and estimating fire emissions can be quite complex so datasets of fire emissions have been created for the community. Examples of these datasets is the Fire Inventory from the National Center for Atmospheric Research or the Global Fire Emissions Database.
