A long-range transport model in East Asia with detailed models for wet deposition processes was developed. The parameters in this model comprised meteorological data, and both in-cloud scavenging process and below-cloud scavenging process with chemical reactions were included in the model. Not only anthropogenic pollutants but natural sulfur compounds such as SO2 from volcanos, DMS from ocean and land soil, and H2S from vegetation were considered as sources of sulfur compounds. We adopted 60 km×60 km grid, oblique-terrain cordinate system, and wind fields were simulated with objective analysis. With the model, atmospheric concentrations and deposition fluxes of SO<SUB>2</SUB> and SO<SUB></SUB>4<SUP>2-</SUP> in Feb. and Aug. of 1993 were calculated. Estimated deposition fluxes were in good agreement with the observed data.
