Abstract

During the last decade, dimethyl sulfide (DMS) has been invoked as an important source of non-anthropogenic sulfur (Andreae et al., 1983; Nguyen at al., 1983). Produced by marine phytoplankton, DMS is transferred to the marine boundary layer (MBL) where it is oxidized to sulfur dioxide (SO 2),methanesulfonic acid (MSA) and to sulfuric acid (H 2 SO 4). The relationship between DMS emission, cloud condensation nuclei (CCN) and cloud albedo is a problem of climatic interest (Charlson et al., 1987) to be treated on the mesoscale due to the fact that the processes involved in DMS-oxidation in the MBL have timescales typically of the order of some hours or less.
