Dimethylsulphide (DMS) is the major biogenic sulphur source gas. It is known to be oxidised by OH and NO 3 to ultimately yield sulphate particles which are important in acid deposition and are also involved in the atmospheric radiative balance. In the laboratory BrO has also been shown to oxidise DMS. Here I present atmospheric model calculations based on inorganic Bromine measurements and find that oxidation by BrO is a sink for DMS.
