(1) MeetingsMeetings for satellite observation of ice sheet, glacier and sea ice were held three times. The subjects were "Project of sea ice and ice sheet observation using RADARSAT SAR", "Glaciological observation by passive micro wave sensors", "Problems on sea ice observation", "Automatic weather stations in Autarctica", "Image analysis by SAR interferometory method", "Ground truth program on Okhotsk sea ice", and so on.(2) Observation in Okhotsk SeaAs a observation in Ground truth program on Okhotsk sea ice, infrared image observation from an airplane and meteorological observation were done around Saroma Lake and Okhotsk Sea when J-ERS1 and RADARSAT came in 1996 and 1997. The infrared temperature of sea ice surface depended on ice thickness.(3) Observation in Antarctic ice sheetAt Syowa Station in Antarctica, several kinds of satellite data were acquired by a multipurpose antenna. SAR images shows the back-scatter signal was large in coastal regions on the ice sheet and small in inland region. To clarify this feature, weather stations using data loggers were set up along a route from Syowa Station to Dome Fuji Station. Two weather stations using ARGOS System are also set up at Dome Fuji and Relay Point in corporation with Wisconsin University.
