  abstract = {{T}he global sulphur cycle has been simulated using a general circulation model with a focus on the source and oxidation of atmospheric dimethylsulphide ({DMS}). {T}he sensitivity of atmospheric {DMS} to the oceanic {DMS} climatology, the parameterisation of the sea-air transfer and to the oxidant fields have been studied. {T}he importance of additional oxidation pathways (by {O}<sub>3</sub> in the gas- and aqueous-phases and by {B}r{O} in the gas phase) not incorporated in global models has also been evaluated. {W}hile the global {DMS} flux is well constrained at 24-27 {T}g {S} yr <sup>-1</sup>, there are large differences in the spatial and seasonal distribution of the atmospheric {DMS} flux generated from the three climatologies of oceanic {DMS} considered here. {T}he relative contributions of {OH} and {NO}<sub>3</sub> radicals to {DMS} oxidation depends critically on which oxidant fields are prescribed in the model. {O}xidation by {O}<sub>3</sub> appears to be significant at high latitudes in both hemispheres. {O}xidation by {B}r{O} could be significant even for {B}r{O} concentrations at sub-pptv levels in the marine boundary layer.},
