P(論文) In order to obtain a better understanding of the character of the aerosol in "clean" air, a series of continuous aerosol measurements was carried out at Syowa Station, Antarctica for two consecutive years (February 1977-January 1979) with emphasis on the chemistry of individual aerosols. From the annual and meteorological variations in the concentration and size distribution of size-fractionated aerosols together with the physical and chemical properties of individual aerosols, it is found that the antarctic aerosol is characterized by the presence of newborn sulfuric acid aerosols, and that aged ammonium sulfate aerosols coexist with sea salt aerosols. Some of the implications of the present findings in relation to the origin of the antarctic aerosol are discussed. departmental bulletin paper
