Dimethyl sulfide and its oxidation products in the atmosphere of the Atlantic and Southern Oceans, Atmos
Abstract--Dimethyl su fide, methane sulfonate, non-sea-salt sulfate and sulfur dioxide concentrations i air were obtained uring a cruise between the U.K. and the Antarctic during the period October 1992-January 1993. In equatorial regions (30°N to 30°S) the atmospheric DMS concentration ranged from...
