Abstract
A box model of DMS oxidation in the clean, low-NO, marine atmospheric boundary layer has been used to predict the latitude dependence of the aerosol methanesulfonate to non sea-salt sulfate ratio. The observed latitude dependence of this ratio in the Southern Hemisphere can be re produced reasonably well if the full suite of reactions proposed by Yi n ct al. (1990a) is employed, and a strong temperature dependence is s pecified in the rates of decomposition of CH3SO2 and CH3SO3 radicals.
