Biogenic emissions modeling for Southeastern Texas
- Texas Natural Resource Conservation Commission, Austin, TX (United States); and others
The Texas Natural Resource Conservation Commission (TNRCC) modeling staff performed biogenic hydrocarbon emissions modeling in support of gridded photochemical modeling for ozone episodes in 1992 and 1993 for the Coastal Oxidant Assessment for Southeast Texas (COAST) modeling domain. This paper summarizes the results of the biogenic emissions modeling and compares preliminary photochemical modeling results to ambient air monitoring data collected during the 1993 COAST study. Biogenic emissions were estimated using BIOME, a gridded biogenic emissions model that uses region-specific land use and biomass density data, and plant species-specific emission factor data. Ambient air monitoring data were obtained by continuous automated gas chromatography at two sites, one-hour canister samples at 5 sites, and 24-hour canister samples at 13 other sites. The concentrations of Carbon Bond-IV species (as determined from urban airshed modeling) were compared to measured hydrocarbon concentrations. In this paper, we examined diurnal and seasonal variations, as well as spatial variations.
