The use of two cosmogenically produced nuclides in the atmosphere, S-35 (half-life = 87 days) and Be-7 (half-life = 53 days), as tracers of gaseous SO2 and aerosol SO4 and Be removal processes to the earth's surface is explored. Based on S-35 and Be-7 wet precipitation fluxes and (S-35)O2, (S-35)O4 and Be-7 concentrations in air samples in the planetary boundary layer at New Haven, Connecticut (USA) coefficients for in-cloud scavenging of (S-35)O2, oxidation of (S-35)O2 to (S-35)O4 in both the planetary boundary layer and the free troposphere, and dry deposition are determined. In addition, the distributions of (S-35)O2, (S-35)O4 and Be-7 between the planetary boundary layer and the free troposphere are determined as well as the air exchange coefficient between the two reservoirs. Application to stable S yields a dry deposition flux to total flux ratio of about 0.20 for August, 1990.
