MSA (methane sulfonic acid) and nssSO_4 showed their maximum in size distribution at 0.2-0.3 micron. Their distribution curves run parallel with similar trend and strongly suggest their same or closely related origin. Na has its maximum at 0.6-0.7 micron; its marine origin is indicated by the similar trend of Mg and also by the Mg/Na ratio close to that in seawater. Therefore, MSA and nssSO_4 ratio at the peak of size distribution was at nearly 0.1,which is higher than 0.2 over the Antarctic sea and at Syowa Station, and suggests their supply from a warmer low-latitude sea area.}, title = {CHEMISTRY OF ANTARCTIC ATMOSPHERIC AEROSOLS}, volume = {6}, year = {1992} }
