| Abstract |
Ten different ways of applying the Gaussian plume diffusion model to represent air quality in an urban area are compared. The different techniques include different degrees of detail in representing spatial and temporal variations in emissions and in meteorological conditions. The methods used to represent spatial and temporal variations are described. It is shown that some improvement results from the use of more detailed spatial and temporal variations. It is suggested that greater improvements would result if more detailed measurements of emissions and meteorological conditions were available. The report places primary emphasis on the use of the Sampled Chronological Input Model (SCIM) as a computer program for the multiple-source Gaussian plume diffusion model; the characteristics of this program are described. |
