Abstract

This paper describes a simplified method, the smeared concentration approximation (SCA) method, developed to characterize air pollution dispersion on the local scale. The SCA method is intended for use in models and analysis concerned with long term policy analysis at the regional level. The methodology centers around the development of SCA dispersion parameters for short-range transport (urban scale) for each of three emission classes: low-level area sources, medium-level point sources, and high-level point sources. Development of the SCA dispersion parameters, using detailed air pollution dispersion models, is described. An SCA dispersion kit for each of the three emission classes is given. Validation of the SCA method and examples of its use are discussed. Some typical questions concerning the use of the SCA method are also discussed. In an Appendix, an example is worked through to show how the SCA dispersion kits are used to develop each SCA dispersion parameter.
