Extract

Dimethyl sulphide (DMS) and its oxidation products (e.g. methanesulphonic acid, MSA) are known to play important roles in atmospheric chemistry (Liss et al. 1997). They act as source of atmospheric particles, and affect the radiative balance of the atmosphere directly by absorbing and scattering solar radiation or indirectly by forming cloud condensation nuclei, which enhance cloud albedo (Charlson et al. 1987, Curran & Jones 2000).
