CRSTER: Single Source Dispersion Model

CRSTER is a stationary gaussian model to compute the concentrations from point sources (max 19) in an urban or rural environment. It shows the two highest concentration values at a given receptor site over periods of 1, 3, 24 hours, and 1 year. It can be used for short range, flat terrain pollution simulation from a non reactive primary pollutant.

KEYWORDS

area: air quality
objectives: simulation
description: gaussian plume, urban site, rural environment, short range, short term, inactive pollutant
