The authors present an analysis of carbonyl sulfide (OCS) in the earth`s atmosphere, with the objective being to assess its role in the formation of sulfate aerosols in the stratosphere. They review the amount of OCS in the atmosphere, its distribution between the troposphere and stratosphere, the estimated source term for emission to the atmosphere, and from one-dimensional model calculations infer a stratospheric lifetime to photochemical reactions of ten years. Calculations infer a sulfur production rate from OCS oxidation which is a factor of 2 to 5 less than recent sulfur aerosol estimates would infer. They discuss a number of possible explanations for the discrepancy.
