Accurate meteorological and photochemical modeling efforts are necessary to understand the measurements
made during the Texas Air Quality Study (TexAQS-II). The main objective of the study is to understand the
meteorological and chemical processes of high ozone and regional haze events in the Eastern Texas, including
the Houston-Galveston metropolitan area. Real-time and retrospective meteorological and photochemical model
simulations were performed to study key physical and chemical processes in the Houston Galveston Area. In
particular, the Vertical Mixing Experiment (VME) at the University of Houston campus was performed on selected
days during the TexAQS-II. Results of the MM5 meteorological model and CMAQ air quality model simulations
were compared with the VME and other TexAQS-II measurements to understand the interaction of the boundary
layer dynamics and photochemical evolution affecting Houston air quality.
