Concentratio of the Aitken Particles Observed at Syowa Station, Antarctica : A Preliminary Report (Special Issue of the Proceedings of the First Symposium on Antarctic Meteorology and Glaciology)

Abstract

Concentration of Aitken particles was measured by means of an improved Pollak type counter for a period of one year from February 1977 to January 1978 at Syowa Station (69.0°s, 39.6゜E), Antaictica Concentration of Aitken particles was lower in the winter season than in the summer season, thus revealing an annual variation. Concentrations of 50 to 100 cm^ were predommant in the winter season and concentrations of 200 to 300 were common in the summer season. However, the concentrations varied largely from day to day due to weather conditions. Especially, concentrations of aerosols increased during a snowstorm (blizzard) even in the winter season and the value exceeded 1000 narticles cm^
