Regional transport model of atmospheric sulfates

Description: A regional transport model of atmospheric sulfates was developed. This quasi-Lagrangian three-dimensional grid numerical model uses a detailed SO/sub 2/ emission inventory of major anthropogenic sources in the eastern U.S. region and observed meteorological data during an episode as inputs. The model accounts for advective transport and turbulent diffusion of the pollutants. The chemical transformation of SO/sub 2/ and SO/sub 4//sup 2 -/ and the deposition of the species at the earth's surface … more
