中国典型积雪区线路积雪观测数据集（2017-2021年）

本数据集包含我国典型积雪区9条积雪观测线路的2017-2021年4个积雪季共38次901个剖面的积雪观测（其中3号线包括2019-2020年的观测数据，4号线包括2019-2020年、2020-2021年的数据）。空间上覆盖了东北-内蒙古、新疆和青藏高原中国三大典型积雪区，时间范围为2008-2021年；观测要素涵盖积雪深度、湿度、密度、粒径、分层、分类，积雪比表面积、光谱反射率、BRDF、反照率、微波辐射亮温，雪剖面分层密度、温度、湿度、粒径、介电常数，积雪环境照片、空气温度、土壤温度、土壤体积含水量、土壤电导率、土壤复介电常数等；数据集包含36个文件夹，857个文件，有xls/txt/doc/jpg/png等多种格式，共327MB。

This dataset contains snow cover observations of 901 snow profiles collected across 38 field campaigns during four snow seasons from 2017 to 2021 at nine snow observation transects in China's typical snow-covered regions. Specifically, observation data from the 2019-2020 snow season is included for Transect 3, while Transect 4 covers data from the 2019-2020 and 2020-2021 snow seasons. Spatially, the dataset encompasses three major typical snow-covered regions in China: Northeast China-Inner Mongolia, Xinjiang, and the Qinghai-Tibet Plateau. The overall temporal scope of the dataset spans from 2008 to 2021. Observation variables include snow depth, snow moisture content, snow density, snow grain size, snow stratification, snow classification, specific snow surface area, spectral reflectance, Bidirectional Reflectance Distribution Function (BRDF), albedo, microwave brightness temperature, stratified density, temperature, moisture content, grain size and dielectric constant of snow profiles, snow environment photographs, air temperature, soil temperature, soil volumetric water content, soil electrical conductivity, complex dielectric constant of soil, and other relevant parameters. The dataset consists of 36 folders and 857 files in multiple formats including xls, txt, doc, jpg, png, etc., with a total size of 327 MB.
