Variability of atmospheric dimethylsulphide over the southern Indian Ocean due to changes in ultraviolet radiation
International audience Dimethylsulphide (DMS) is a climatically important component of global biogeochemical cycles, through its role in the sulphur cycle. Changes in ultraviolet radiation (UV) exhibit both positive and negative forcings on the dynamics of production and turnover of DMS and its prec...
