Review of development and application of CRSTER and MPTER models

Abstract

The CRSTER and MPTER computer codes are two of many air quality dispersion models recommended for use in a regulatory context by the U.S. Environmental Protection Agency. CRSTER and MPTER are generally applicable to tall stack sources, such as coal-fired electrical utility power plants located in flat or gently rolling terrain. This paper briefly reviews the developmental history, formulation, operation and application of the CRSTER and MPTER models. Also reviewed are performance evaluation studies which have included these two models. The paper concludes with a brief discussion of future directions for regulatory modeling of tall stack sources.
