2008年3月29日在冰沟流域加密观测区开展的KaK波段机载微波辐射计航空遥感地面同步观测，为积雪微波辐射特性及参数反演，尤其是雪深与雪水当量研究提供了基本数据集。\n
\n观测内容包括：\n
\n1）雪特性分析仪观测，观测变量雪密度、雪复介电常数、雪体积含水量、雪重量含水量等，该测量在样地BG-A进行。\n
\n2）积雪参数观测，包括雪深（塑料直尺），分层雪深温度（针式温度计两个测量值的平均值），雪粒径（手持显微镜），雪密度（环刀法）及卫星过境时同步的雪表面和雪土界面温度温度（手持式红外温度计），该观测分别在4个样地BG-A、BG-B、BG-EF、BG-I进行，其中BG-A测量（18个点），其它3个样地测量20个点。分层标准为挖积雪剖面，自上而下每10cm均匀分层，如果最后剩下的深度超过10cm而不足15cm则以一层划分。\n

The Kak band airborne microwave radiometer aerial remote sensing ground synchronous observation was carried out in the intensive observation area of Binggou basin on March 29, 2008, which provides a basic data set for the inversion of snow microwave radiation characteristics and parameters, especially the study of snow depth and snow water equivalent.\n
\nObservation contents include:\n
\n1) The snow characteristic analyzer observes the variable snow density, snow complex dielectric constant, snow volume water content, snow weight water content, etc. the measurement is carried out in sample plot bg-a.\n
\n2) Snow parameter observation, including snow depth (plastic ruler), layered snow depth temperature (average of two measured values of needle thermometer), snow particle size (hand-held microscope), snow density (ring knife method) and synchronous snow surface and snow soil interface temperature during satellite transit (hand-held infrared thermometer). The observation was carried out in four sample plots bg-a, bg-b, bg-ef and bg-i respectively, Bg-a measurement (18 points) and 20 points in the other 3 sample plots. The stratification standard is the snow digging profile, which is evenly layered every 10cm from top to bottom. If the last remaining depth is more than 10cm but less than 15cm, it is divided into one layer.\n
\nThe dataset includes two folders: original data and preprocessed data.
