Short summary
Levels of MSA and sulfate at inland Antarctica are documented from multiple year-round records of bulk and size-segregated aerosol samplings. A striking difference in the seasonality of sulfur aerosol composition, characterized by a MSA to nssSO4 ratio reaching a minimum in summer over the Antarctic plateau (0.05) and a maximum at the coast (up to 0.40), is clearly established. An efficient chemical destruction of MSA is suggested to take place over the Antarctic plateau in summer.
