Abstract
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.
