摘要：

Be-10 is used as a spike of the natural background atmospheric aerosol to calculate the global flux of sulfur (F(s)) into the free troposphere. The sulfate and Be-10 concentrations determined in polar snow are compared. On the basis of an annual Be-10 production rate of 1.21 10(6) at.cm-2, a very low figure of 2.9 Tg S a-1 is calculated for F(s) which suggests that most of the sulfur emitted at ground level remains in the boundary layer. The role of OCS in the upper tropospheric sulfur budget is reviewed. It is also shown that cataclysmic volcanic eruptions may disturb considerably for 1-2 years this vast background tropospheric sulfur reservoir.
