Long-range transport of sulfur in the western United States. [Projections for 1985 and 1990]

Description: Pollutants, such as SO/sub 2/ and sulfate, emitted from both utility and industrial coal burning processes have long residence time in the atmosphere. Therefore, the long-range atmospheric transport and diffusion of these pollutants must be considered in any environmental assessment of proposed plant operation. The most useful tool in predicting the long-range transport of pollutants is a computer simulation technique for the Gaussian diffusion equation. Information produced by the model includ… more
