This paper examines the application of a photochemical grid model to the problem of assessing the effect of emission control measures on the formation of photochemical smog in urban areas. Simulations are carried out using the Urban Airshed Model together with a data base for the city of Tulsa, Oklahoma. The model is first evaluated as an ozone predictive tool by comparing model predictions with air quality observations. The model is then employed to estimate ambient ozone concentrations associated with various projections of future emission levels. The Tulsa study is part of a larger EPA program for demonstrating and evaluating the use of photochemical grid models for air quality planning and management activities related to ozone. Other cities included in the program for which studies have been completed are St. Louis, and Denver. A data base has been assembled for Philadelphia and modeling efforts are now underway. Other groups have sponsored studies with the Urban Airshed Model in Los Angeles and with an earlier version of the model in Sacramento, Denver, and Los Angeles.
