Sulfur-containing species (sulfate and methanesulfonate) in coastal antarctic aerosol and precipitation
The concentrations of sulfur-containing species (sulfate and methanesulfonate (MSA)) of aerosols collected at three coastal Antarctic sites (Neumayer, Dumont d'Urville, and Halley) have been studied in order to investigate the natural sulfur cycle at high southern latitudes. The multiple-year d...
