(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.

(1)会议召开了三次冰盖、冰川和海冰卫星观测会议。课题为“RADARSAT SAR海冰和冰盖观测项目”、“被动微波传感器冰川观测”、“海冰观测问题”、“南极自动气象站”、“SAR干涉法图像分析”、“鄂霍次克海冰地面真相程序”等。(2)鄂霍次克海的观测作为鄂霍次克海冰地面实况项目的观测，在1996年和1997年J-ERS1和RADARSAT抵达时，在萨罗马湖和鄂霍次克海附近进行了飞机红外图像观测和气象观测。海冰表面的红外温度与冰层厚度有关。(3)南极冰盖观测在南极Syowa站，利用多用途天线获取了几种卫星数据。SAR图像显示，冰盖沿海地区的后向散射信号较大，内陆地区的后向散射信号较小。为了阐明这一特征，使用数据记录器的气象站沿着从Syowa站到Dome Fuji站的路线建立。此外，天文台亦与美国威斯康辛大学合作，在多姆富士及中继点设立两个使用ARGOS系统的气象站。
