2008年03月16日22:33-17日15:00在阿柔样方3北侧开展多角度地基散射计连续观测，主要观测阿柔草场地表冻融循环引起的后向散射系数时间序列变化特征。\n
\n具体包括：针式温度计获得的0-5cm平均土壤温度；玻璃管地温计测量的5cm和10cm处土壤温度；POGO便携式土壤水分传感器测量的土壤温度、土壤体积含水量、损耗正切、土壤电导率、土壤复介电常数实部及虚部；以及100cm^3环刀取土经烘干获得的土壤重量含水量、土壤容重及体积含水量。本数据可为发展和验证主动微波遥感反演土壤水分及冻融状态算法提供基本的地面数据集。\n
\n本数据集包括2个文件，分别为：散射计观测场地面观测数据和散射计观测数据，都以Excel格式存储。

\nSpecifically, it includes: 0-5cm average soil temperature obtained by needle thermometer; Soil temperature at 5cm and 10cm measured by glass tube geothermometer; The real and imaginary parts of soil temperature, soil volume water content, loss tangent, soil conductivity and soil complex dielectric constant measured by pogo portable soil moisture sensor; And the soil weight water content, soil bulk density and volume water content obtained by drying 100cm ^ 3 ring knife soil. This data can provide a basic ground data set for the development and verification of active microwave remote sensing algorithm for retrieving soil moisture and freeze-thaw state.\n
