Abstract |
A Lagrangian photochemical air quality simulation model has been adapted to the St. Louis, Missouri/Illinois metropolitan region and the Regional Air Pollution Study (RAPS) aerometric and emissions data base. This adaptation was performed to provide a means for EPA to independently assess the validity of a state-of-the-art Lagrangian photochemical model. Chemical kinetic oxidation mechanisms involving hydrocarbons, nitrogen oxides and sulfur oxides and a vertical diffusion formulation developed by Environmental Research and Technology Inc. for modeling reactive pollutants in the troposphere are described. Methods for determining model input parameters are discussed and model results for ozone, nitrogen dioxide, carbon dioxide, sulfur dioxide, and sulfate are presented for three summer days in 1976. In considering so few simulations, no firm conclusions concerning model reliability are possible, although predicted pollutant concentrations are of reasonable levels. Most noteworthy for future users, the results suggest that the model may predict less ozone than is actually generated in St. Louis. Uncertainty in initial conditions of ozone and organic species is likely responsible for this discrepancy between observed and computed values. |
