Dallas-Fort Worth Eight-Hour Ozone SIP Modeling (2006 Episode)
Air quality modeling data files and documents for the eight-hour ozone SIP revision for the DFW area (2006 episode).
The TCEQ conducted meteorological and photochemical modeling to support development of the State Implementation Plan in the Dallas-Fort Worth (DFW) ozone nonattainment area for the 1997 eight-hour ozone standard. This page provides the data files and documents for the DFW Ozone Modeling of the June 2006 Episode (DFW8H2).
If you have any question regarding these files, please e-mail us at amda@tceq.texas.gov with "DFW8H2 Ozone SIP Modeling Files" in the subject line.
