SMOKE Data

SMOKE input data consist of emissions inventories, temporal and chemical speciation profiles, spatial surrogates, gridded meteorology and land use data, and other ancillary files for specifying the timing, location, and chemical nature of emissions. SMOKE is distributed with example data for getting started with the model. The example files distributed with SMOKE are for demonstration purposes only, they are not meant for real-world modeling applications.

The primary source for non-meteorology SMOKE input data is the U.S. EPA Clearinghouse for Inventories and Emissions Factors (CHIEF). The U.S. EPA Office of Air Quality Planning and Standards (OAQPS) Emissions Inventory and Analysis Group (EIAG) provides SMOKE inputs for different rule-making modeling platforms. These platforms include not only the NEI for both criteria air pollutants (CAPs) and hazardous air pollutants (HAPs), but also all of the SMOKE ancillary data files created by EPA for use in SMOKE. EPA uses CHIEF to provide these data.

Meteorology data must be generated for specific SMOKE applications using either MM5, WRF, or a similar model. The output data from meteorology models must be formatted for SMOKE using a program like MCIP.
