Model performance, sensitivity and control strategy simulations have been performed to evaluate the Urban Airshed Model potential for estimating ozone concentration control requirements for urban areas which do not meet the national ambient air quality standard (NAAQS) for ozone. The simulations were conducted with a 1975-76 emission inventory and meteorological data base for St. Louis, Missouri. An analysis of the model performance simulation results suggests that the Urban Airshed Model (UAM) succeeds rather well in reproducing observed peak ozone concentrations within the modeling region. Model bias and precision data suggest that the UAM tends to underpredict ozone concentrations within the modellng region. The degree of underprediction increases with increasing ozone concentration. The observed diural variation in ozone concentration is replicated reasonably well by the UAM; however, the spatial distribution is replicated less well. Model evaluation results suggest that the UAM is sufficiently accurate and precise for control strategy analysis.
