Numerous intermediates such as dimethyl sulfoxide (CH 3SOCH 3: DMSO), methanesulfinic acid (CH 3S(O)OH: MSIA), dimethyl sulfone (CH 3SO 2CH 3: DMSO 2) and CH 3SO x(x = 0−3) radicals can be formed through the subsequent reaction 5, 10. The reactions with OH radical during the day time 5, 7 and with NO 3 radical 5, 8, 9 in the night initiate the DMS oxidation, and these reactions can be classified as adduct reactions and abstraction reactions. The oxidation of dimethyl sulfide is considered of great importance in the marine boundary layer, because the main oxidation products, methanesulfonic acid (MSA) and sulfuric acid, can contribute to the formation of non-sea salt sulfate (nss-SO 4 2−) aerosol, which can act as the cloud condensation nuclei and can promote the formation of marine stratus clouds 4, 5, 6.
