2008年3月22日在冰沟流域加密观测区开展的高光谱卫星EO-1 Hyperion地面同步观测，为积雪遥感参数反演提供了基本数据集。\n
\n观测内容包括：\n
\n1）雪表面比辐射率观测（便携式比辐射率测定仪测量），测量位置为冰沟寒区水文气象观测站旁。\n
\n2）雪特性分析仪观测，参数包括有雪密度、雪复介电常数、雪体积含水量、雪重量含水量等，该测量在BG-A样区进行，测量时间为北京时间（BJT）2008年3月2日11:20-13:53。\n
\n3）积雪参数观测，该观测分别在BG-A、BG-B、BG-C、BG-D、BG-E、BG-F6个样地进行。测量变量包括卫星分层雪深温度（针式温度计测量），雪粒径（手持式显微镜测量），雪密度（铝盒方式测量），卫星过境时同步的雪表面和雪土界面温度（手持式红外温度计测量）。\n
\n4）除了卫星同步外，当天还开展了高光谱航空遥感试验，由于高光谱仪器出现问题，没有完成整个航带的飞行。因此只有部分小组在飞机过境时刻测量了地表红外温度（BG-D、BG-E、BG-B、BG-F）。\n

The hyperspectral satellite EO-1 Hyperion ground synchronous observation was carried out in the intensive observation area of Binggou basin on March 22, 2008, which provides a basic data set for snow remote sensing parameter inversion.\n
\nObservation contents include:\n
\n1) The specific emissivity of snow surface (measured by portable specific emissivity meter) is measured next to the hydrometeorological observation station in Binggou cold area.\n
\n2) The snow characteristic analyzer observed that the parameters include snow density, snow complex dielectric constant, snow volume water content, snow weight water content, etc. the measurement was carried out in bg-a sample area at 11:20-13:53 Beijing time (BJT) on March 2, 2008.\n
\n3) Snow parameter observation, which is carried out in bg-a, bg-b, bg-c, bg-d, bg-e and bg-f6 sample plots respectively. The measured variables include satellite layered snow depth temperature (measured by needle thermometer), snow particle size (measured by hand-held microscope), snow density (measured by aluminum box), synchronous snow surface and snow soil interface temperature during satellite transit (measured by hand-held infrared thermometer).\n
\n4) In addition to satellite synchronization, hyperspectral aerial remote sensing experiments were carried out on the same day. Due to problems with Hyperspectral instruments, the flight of the whole flight belt was not completed. Therefore, only some teams measured the surface infrared temperature (bg-d, bg-e, bg-b, bg-f) at the time of aircraft transit.\n
\n5) New snow albedo observation (using portable albedo meter), the measurement position is in the east outside sample A2.\n
\n6) Snow spectral observation (portable spectrometer: provided by Xinjiang Meteorological Bureau and Nanjing University), with GPS data records.\n
\nThe dataset includes two folders: original data and preprocessed data.
