User's guide to the Rough-Terrain Diffusion Model (RTDM) (Rev. 3. 20)

Technical Report ·
OSTI ID:5246798

The User's Network for Applied Modeling of Air Pollution (UNAMAP), Version 6 (Revised 1/88) contains 30 air-quality simulation models. These models input emission and meteorological data to calculate projected air-pollutant concentrations. UNAMAP contains state-of-the-art dispersion research algorithms funded by the EPA's Office of Air Quality Planning and Standards for Environmental Impact Analysis. The manual describes a sequential version of the Rough Terrain Diffusion Model (RTDM, version 3.20). The model provides a method to estimate air-pollutant concentrations from multiple co-located sources in a rural environment. RTDM can be used in flat or complex terrain, but it is especially suited for use in complex terrain.
