2008年4月5日-8日期间，在阿柔加密观测区平整裸土（N38º03.639'；E100º26.793'；2998m）开展了多频率多极化多角度的地基微波辐射计连续观测，包括S波段地基微波辐射计观测（4月6日-8日），C波段地基微波辐射计观测（2008年4月7日-8日），K波段地基微波辐射计观测（4月5日-8日）及Ka波段地基微波辐射计观测（4月5日）。\n
\n主要观测目标为地表的冻融状态对微波亮温的影响。该场地为平整裸土，初始含水量较干约14%，后经人工均匀浇水，含水量可达30%左右。土壤水热观测场布置在微波辐射计观测场东侧，包括5cm土壤温度自动观测（10分钟观测步长）；5cm，10cm，20cm和30cm土壤温度人工观测（采用针式温度计，1小时观测步长）；5cm，10cm，20cm和30cm土壤水分自动观测（10分钟观测步长）。本数据可为发展冻/融土壤的微波辐射传输正向模型和微波遥感反演模型提供基础数据。\n
\n本数据集包括7个文件，分别为：S波段地基微波辐射计观测数据，C波段地基微波辐射计观测数据，K波段地基微波辐射计观测数据，Ka波段地基微波辐射计观测数据，土壤温度自动观测数据，温度人工观测数据，土壤水分自动观测数据。其中水分数据和温度数据都以Excel表格存贮。
