Report on meteorological research observations by the 29th Japanese Antarctic Research Expedition in 1988

A 5-year project of "Antarctic Climate Research (ACR)" has been started from the 28th Japanese Antarctic Research Expedition (JARE-28) in 1987. In 1988 (JARE-29), 2 major items of observation were carried out under the subject of interannual variation of Antarctic atmosphere. 1) Observations of cloud and precipitation using vertical pointing meteorological radar, dual-wave microwave radiometer and NOAA satellite data. 2) Monitoring of atmospheric minor constituents. At Asuka Station surface synoptic observations and radiation measurements were made. Moreover, 2-unmanned stations were newly built and some other observations on the sea-ice and ice-sheet were carried out.
