Houston-Galveston-Brazoria 8-Hour Ozone SIP Modeling (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.

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
