Abstract |
The rough terrain diffusion model (RTDM3.2) 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 is in compressed format but a dearchive utility is included. |
