Abstract
The relationship between the steady state cloud condensation nuclei (CCN) concentration and the dimethylsulfide (DMS) emission flux in remote marine regions is investigated by modeling the principal gas-, aerosol-, and aqueous-phase processes in the marine boundary layer (MBL). Results are in reasonable quantitative agreement with the available measurements of DMS, SO_2, H_2SO_4, CCN, and condensation nuclei (CN) concentrations in remote marine regions of the globe and suggest that indeed DMS plays a major role in the particle dynamics of the MBL. For sufficiently low DMS fluxes practically all the SO_2 produced by DMS photooxidation is predicted to be heterogeneously converted to sulfate in sea-salt aerosol particles. For DMS fluxes higher than approximately 2.5 μmole m^(−2)d^(−1) a linear relationship is found to exist between the CCN number concentration and the DMS flux.
