Based on experimental data collected during cruise 15/3 of R/ V Meteor in the tropical South Atlantic (19°S), the marine sulfur cycle has been simulated with a one-dimensional coupled meteorological-chemical model. The potential of sea-spray aerosols to act as a sink for SO2 produced from dimethylsulfide (DMS) oxidation has been examined by using a simple humidity and height dependent parameterization for sea salt aerosol distribution. Simulations show significant reduction of total SO2 concentrations to 27-82% of the values found in the absence of this heterogenous process. -from Authors
