RAM is an air-quality model based on the Gaussian-plume simplication of the diffusion equation which assumes time independence in the input meteorology and concentration. The model is primarily used to determine short-term (one hour to one day) concentrations from point and area sources. A maximum of 250 point sources and 100 area sources can be considered to yield pollutant concentrations at a maximum of 180 receptors. The simulation is done using hourly meteorological data for periods ranging from one hour to one year. A default option is available in the model for regulatory applications. Use of this option automatically sets certain parameters to preassigned values for consistency with the Guideline on Air Quality Models (Revised) (EPA, 1986).
