Houston-Galveston-Brazoria 8-Hour Ozone SIP Modeling (2000 Episode)

Air quality modeling data files and documents for the 8-Hour Ozone SIP in the Houston-Galveston-Brazoria area (2000 episode).

The TCEQ conducted meteorological and photochemical modeling to support controls on ozone pollution under the State Implementation Plan in the Houston-Galveston-Brazoria (HGB) ozone non-attainment area for the eight-hour ozone standard. Details on the attainment demonstration modeling setup are provided below.

If you have any question regarding these files, please e-mail us at amda@tceq.texas.gov with "HGB 8-Hour Ozone SIP Modeling Files" in the subject line.

Photochemical Modeling Data Files

CAMx Modeling Domain - map projection, horizontal grid and vertical layer structures.

Air Monitoring Sites - information of air quality and meteorological monitoring sites in HGB area.

Observed Air Quality Data (MS Excel) - O3, NO, NO2, CO, and VOC data from monitoring sites in the HGB area on Aug. 15–Sept. 7, 2000.

MM5 Modeling of August 16 – September 6, 2000 HGB Ozone Episode

Run Name Main Features
TCEQuh1 - Grell cumulus schemes for 108, 36, and 12km domains; no cumulus scheme for 4km domain.
- Analysis nudging was used for 108, 36, and 12km domains; observational nudging using profiler data was used for 4km domain.
- MRF PBL scheme.
- RRTM radiation.
- Texas Forest Service (TFS) Landuse data for hgbpa_04km domain.
- Modified NOAH Land-surface model to use TFS Landuse.
TCEQuh1_eta - Same as TCEQuh1 except using ETA instead of MRF PBL scheme.
- Modification to the emissivity in NOAH LSM to improve temperature predictions.
- Standard landuse data.
- 4km domain only
