Gaussian Plume Air Dispersion Model

1.4 Purpose of Document

The purpose of this document is to describe the technical formulation of AERMOD and its preprocessors. Our intent is to provide model developers, peer reviewers and model users with a comprehensive listing of all significant algorithms contained in the model. Performance and evaluation of the current model are described in other reports (Lee et al., 1998b; PES, 1998).
