Dimethyl sulfide

From Glossary of Meteorology



dimethyl sulfide

Naturally occurring sulfur gas, formula CH3SCH3, emitted predominantly by phytoplankton, marine algae, seaweed, etc.

Dimethyl sulfide (DMS) has the highest flux to the atmosphere of all biogenic sulfur gases. The oxidation of DMS has been linked to the formation of aerosol particles in the troposphere remote from urban areas, and thus to the potential for climate regulation.
