A Model of Airflow and Diffusion in Complex Terrain (MADICT).

Abstract

A model of transport and diffusion during time- and space-varying meteorological conditions is described, along with relevant supporting theory. The model calculates 3-dimensional wind fields in complex terrain from limited observational input. Superposition of previously calculated mass-conserving wind field solutions is used to keep the reuqired calculations to a minimum. Limited discussions of the required wind calculations are included, along with listings of applicable computer codes. The transport and diffusion module luses 'puffs' to simulate continuous plume behavior. Techniques are described for minimizing the required calculations. The report includes complete user instructions, a FORTRAN77 computer code and two sample problems for the transport and diffusion model.
