RTDM 3. 2: Rough Terrain Diffusion Model. EPA/ORD (Environmental Protection Agency/Office of Research and Development) air-quality simulation model. Model-Simulation
The Rough Terrain Diffusion Model (RTDM 3.2) is a sequential Gaussian plume model designed to estimate ground-level concentrations in rough (or flat) terrain in the vicinity of one or more co-located point sources. It is designed for applications involving chemically stable atmospheric pollutants and is best suited for elevation of buoyant-plume behavior within about 15 km from the source(s). RTDM has special algorithms to deal with plume behavior in complex terrain. Software Description: The software is written in the FORTRAN programming language for implementation on an IBM model 3090 computer. The model is distributed on a 5 1/4-inch IBM/PC-compatible diskette. Data are in compressed format but a dearchive utility is included.
