Abstract

Emissions of carbonyl sulfide (OCS) and carbon disulfide (CS2) from natural and anthropogenic sources have been estimated consistent with the observed latitudinal and vertical distributions of these trace gases. Anthropogenic emissions appear to be a small part (≤ 25%) of the yearly emissions of OCS and CS2. Oceans and soils are the largest sources, representing about 50% of the yearly emissions of OCS. Biomass burning is perhaps the largest anthropogenic source, while coal-fired power plants and automobiles contribute small amounts. Chemical uses may be the largest anthropogenic source of CS2. The results suggest that the lifetime of OCS is about 2 years and of CS2 about 12 days.
