Sensitivity studies of the air quality modeling systems to assess impact of emissions input uncertainties and meteorological model configurations such as horizontal and vertical grid structures and choice of physical options appear likely to be useful in improving understanding of appropriate ways to simulate Houston's rapid ozone formation events. Simulation results are to be compared with the high ozone events observed during the TexAQS 2000 intensive measurement period. The expected results are: (1) quantification of model sensitivity to the input meteorological model configurations and to the uncertainties in the olefin, biogenic, and NOx emissions and (2) recommended model configurations that facilitate testing of emissions control strategies suggested for use in preparing the mid-course review of the State Implementation Plan and other proposals. The project envisions using the August 23 through September 6, 2000 TxAQ Study period performed using a 36/12/4-km grid and then two 3-day ozone episodes with dynamically contrasting meteorological conditions would be selected for more intensive sensitivity analysis including use of high-resolution grid (1.33 km). A key day from each episode will be selected and approximately 20 MM5 sensitivity simulations would be conducted varying key model options including radiation schemes, PBL, soil moisture, temperature, and cloud parameterization, level of data assimilation, etc.
