MPTER: Multiple Point Gaussian Dispersion Algorithm with Terrain Adjustment

MPTER (Multiple Point Gaussian Dispersion Algorithm with Terrain Adjustment) is a gaussian air pollution model that can be used with multiple point sources, in an urban or rural environment, in flat or moderately complex (no elevations above the pollution sources) terrain conditions. It computes average conccentration values at the receptor sites over periods from one hour to one year. It cannot consider deposition or chemical reactions.
