• This paper describes annual precipitation estimated by blowing snow observations made on a strong katabatic wind slope at Mizuho Station (70°42'S, 44°20'E; 2230m above mean sea level) in East Antarctica. Snowfall densities have been estimated from the asymptotes of the vertical profiles of snow drift density, i. e., a method reported by FOHN (J. Glaciol., 26,469,1980) which separates the amount of snowfall from the drift density in a snowstorm. Using the snowfall densities, fall velocity of blowing snow particles (0.5m/s) and the distribution of number of days with snowfall, the value of annual precipitation in 1980 was estimated as about 140mm in water.
