Effect of meteorological parameters on tropospheric ozone formation in the Texas Upper Gulf Coast Region

Meteorological parameters play an important role in the formation ground level ozone. This study investigates the effects of a number of meteorological parameters on tropospheric ozone formation in the Texas Upper Gulf Coast Region using comprehensive modeling study. A suite of physical models, including mesoscale meteorological model (MM5), Sparse Matrix Operating Kernal Emission (SMOKE) modeling system, and community Multiscale Air Quality (CMAQ) modeling system are use in the study. The meteorological changes are implemented through the MM5 and the results of the effects are obtained using the CMAQ. A base case and four sensitive cases were ultimately defined for the purposes of this study.; Observational data recorded from four monitoring sites in the Houston/Galveston area and three monitoring sites located in the Beaumont/Port Arthur areas have been selected for the model verification. The base case is analyzed by using one of the sensitive cases to get the relation of the tropospheric ozone formation. The sensitive case used for the analysis segment was chosen according to each of their respective performance and meteorological characteristics.
