AIRBORNE OBSERVATION OF WATER VAPOR AND AEROSOLS ALONG MIZUHO ROUTE, ANTARCTICA

元データ 国立極地研究所

概要

Airborne observations of water vapor and aerosols using a dew point meter and optical particle counters were made along the route from Syowa Station (69°00′S, 39°35′E) to Mizuho Station (70°42′S, 44°20′E). Vertical flights were made around Syowa and Mizuho Stations, horizontal flights along the route were made at a height of 3800m a.s.l., which is the altitude of Dome Fuji Station, and return flights from Mizuho Station to Syowa Station were made along the slope at about 300-500m height from the ground snow surface. A typical result, on December 25,showed gradual increase of water vapor amount and some decreases of aerosol concentration from the coast to the inland area along the 3800m flight. On August 30,strong enhancement of aerosol loading was found in the 700 to 900hPa layer, related to the passage of a strong low pressure system. Particle size distribution was steeper in summer and flatter in winter, indicating an increase of large particles and decrease of smaller particles in winter.
