CHEMISTRY OF SNOW, AEROSOLS AND ATMOSPHERIC ACID GAS AT DOME FUJI STATION, ANTARCTICA
A year-round sampling of surface snow, aerosols (using 0.2μm Nuclepore filter) and acid gases (using alkali impregnated filter) was carried out at Dome Fuji Station in the period from February to December of 1995 by the 36th JARE. Samples were transported under refrigeration. The concentration level...
