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) will be providing the SMOKE inputs for its 2002-based modeling platform by the end of calendar year 2006. This platform will include not only the 2002 NEI final (version 2) 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 version 2.3+. EPA will use CHIEF to provide these data.

This 2002 modeling platform will include the following features (although all may not be completed by the end of 2006):

• Support of modeling for criteria and all HAP pollutants (including Hg) with the
  latest toxics-enabled version of CMAQ and the CB05 chemical mechanism.
• Use of the SPECIATE4.0 database, including newly reviewed speciation cross-reference
  and profiles. Speciation profiles for CB-IV, CB05, and SAPRC-99.
• SMOKE-ready inventory files using SMOKE's ORL format, including day-specific
  point-source fires.
• 2002 hourly CEM data for EGU sources
• Data files to support growth and controls to 2009, 2014, and 2020
  • including a new growth approach for EGU toxics based on the IPM-
    generated non-toxic emissions.
  • including hour-specific "average-year" EGU emissions based on the
    latest version of the IPM model.
• All new ancillary data files to work with the 2002 NEI final (version 2)

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.
