Abstract:

The development and implementation of photochemical diffusion models for air quality simulation provide one technique for carrying out the mandates of the 1970 amendments to the Clean Air Act. Mathematical models currently available for evaluating the impact of emissions on air quality consider source emission data, meteorological variables characterizing transport and dispersion processes, and reaction mechanisms describing chemical transformation and removal processes of atmospheric pollutant species. The purpose of this paper is to review and evaluate the status of several photochemical diffusion models currently available. These models, which vary in complexity, were developed to assess the impact of anthropogenic emissions on ambient photochemical oxidant levels in urban aras. Three approaches to photochemical air quality simulation modeling are considered: the grid point model, the trajectory model, and the box model. /Author/
