Abstract: | Observations of annual wet deposition of sulfur made during 1980 at 62 stations in northeastern America are interpreted using a statistical long-range transport model. This work is meant to demonstrate the role of an empirical model in the analysis of observations. Our analysis points to the following conclusions: - 1.(1) The parameters that represent the conversion of SO2 to SO4 and the wet and dry removal of sulfur are insensitive to concentration levels,
- 2.(2) the variation of the wet deposition field is closely related to the distribution of sulfur emissions and
- 3.(3) observations demand efficient wet scavenging of SO2.
