A Review of Transport and Diffusion Models.

Abstract

The modeling techniques for the transport and diffusion of material in the atmosphere is reviewed with emphasis on the impact of terrain and meteorology on the process. Weaknesses and strengths of the various modeling approaches are discussed and a number of models in use by or under development for the Defense community are categorized by type and suggested applicability. The conclusion of this report is that any substantial increase in current modeling capability will require more attention to the high resolution effects of terrain and meteorology. It is further concluded that analytic Gaussian techniques in use are not capable of efficiently providing the necessary coupling to these effects and of the subsequent increase in desired accuracy.
