Abstract The User's Network for Applied Modeling of Air Pollution UNAMAP (Version 4) contains 21 air quality simulation models (AQSM). These models input emission and meteorological data to calculate projected air pollutant concentrations. UNAMAP contains state-of-the-art dispersion research algorithms supported by U.S. Environmental Protection Agency's (EPA) Office of Research and Development. The UNAMAP (Version 4) contains ten (10) new models. In addition, most of the original UNAMAP models have undergone extensive revision. The models are: COMPLEX II - is a multiple point source code with terrain adjustment. COMPLEX I - is a multiple point source code with terrain adjustment representing a sequential modeling bridge between VALLEY and COMPLEX II. BLP (Buoyant Line and Point Source Dispersion Model) - is a gaussian plume dispersion model associated with aluminum reduction plants. RAM - Short-term gaussian steady-state algorithm estimates concentrations of stable pollutants. CRSTER - estimates ground-level concentrations resulting from up to 19 collocated elevated stack emissions. CDM - this climatological dispersion model determines long-term quasi-stable pollutant concentrations. CDMQC - CDM altered to provide implementation of calibration and of averaging time transformations. APRAC - computes hourly averages of carbon monoxide for any urban location. HIWAY - computes the hourly concentrations of non-reactive pollutants downwind of roadways. VALLEY - is a steady-state, univariate gaussian plume dispersion algorithm. TEM (Texas Episodic Model) - is a short term, steady-state gaussian plume model for determining short-term concentrations of non-reactive pollutants. TCM (Texas Climatological Model) is a climatological, steady-state gaussian plume model for determining long-term average pollutant concentrations of non-reactive pollutants. PAL (Point, Area, Line Source Algorithm) - this short-term gaussian steady-state algorithm estimates concentrations of stable pollutantsfrom point, area, and line sources. PTPLU - is a point source dispersion gaussian screening model for estimating maximum surface concentrations for one-hour concentrations. MPTER - is a multiple point-source gaussian model with optional terrain adjustments. HIWAY2 - update of HIWAY. ISCST (Industrial Source Complex Short-Term) is a steady-state gaussian plume model which can be used to access pollutant concentrations from an industrial source complex. ISCLT (Industrial Source Complex Long-Term) - is a steady-state gaussian plume model which can be used to access pollutant concentrations from an industrial source complex. PTMAX - performs an analysis of the maximum short-term concentrations from a single point source as a function of stability and wind speed. PTDIS - Estimates short-term concentrations directly downwind of a point source at distances specified by the user. PTMTP - estimates for a number of arbitrarily located receptor points at or above ground level, the concentrations from a number of point sources...Software Description: The system is written in the FORTRAN programming language for implementation on a UNIVAC 1100/82 computer using the 36R2B operating system. 69K 6-character words are required to operate the lest model of the system.
