Abstract

Dimethylsulfide (DMS), sulfate (SO(4)(2-)), methanesulfonate (MSA) and dimethylsulfoxide (DMSO) measurements were made at two sites in western France. An old lighthouse on the coast at Pointe de Penmarc'h, close to algal beds, a strong source of DMS, was used as the coastal site, with a second site located a few km inland. DMS concentrations averaged 455 pptv and 404 pptv at the lighthouse and the inland site, respectively. At the coastal site sulfate and MSA concentrations of 1.1 ppb and 25 ppt respectively were measured with concentrations of 1.3 ppb and 27 ppt being found at the inland site. From an analysis of the changes in the atmospheric composition of these compounds, a clearer understanding of the atmospheric chemistry of DMS may be gained.
