Houston-Galvestion-Brazoria 1-Hour Ozone SIP Mid-Course Review Modeling (2000 Episode)

Air quality modeling data files and documents for the Houston-Galveston-Brazoria 1-hour ozone SIP mid-course review (2000 episode).

Meteorological and photochemical modeling is conducted to support the State Implementation Plan (SIP) for controlling ozone pollution in the Houston-Galveston-Brazoria (HGB) ozone non-attainment area. This page provides the modeling data files and related documents for Phase II of the Mid-Course Review of the ozone SIP in the HGB area.

If you have any question regarding these files, please send an email to amda@tceq.texas.gov with “HGB Ozone SIP MCR 2000 Episode Modeling Files” in the subject line.

Modeling Protocol

This protocol details procedures the TCEQ used to model ozone in the HGB area using an approved photochemical modeling for Phase II of the ozone SIP MCR as discussed in the December 2002 SIP revision. This modeling will be included in a SIP revision submitted to the U.S. Environmental Protection Agency in April 2004. The modeling will incorporate extending the 2000 episode to further represent the most prevalent meteorological conditions associated with the formation of unhealthy levels of ozone in the region. The modeling included the extended 2000 episode to further represent the most prevalent meteorological conditions associated with the formation of unhealthy levels of ozone in the region. The modeling incorporated refinements of data collected during the 2000 Texas Air Quality Study (TexAQS 2000) and additional scientific advancements. The protocol document includes the main text and three appendixes as PDF files (help with PDF).
