Carbonyl sulfide (COS) is the principal sulfur gas in the atmosphere with a concentration of 500 ppt. Carbonyl sulfide has been proposed as an important climatic gas because it is a source of stratospheric submicron aerosol particles (Crutzen, 1976). The oceans are a major source of dimethyl sulfide ([CHs]2S)(DMS) (Andreae et al., 1985) as are rice paddy fields (Kanda et al., 1991). The other gaseous sulfur species of interest
