本数据集包含我国典型积雪区的6个超级站2017-2020年3个积雪季的人工观测及自动观测的积雪特性数据集。其中，人工观测数据集包括逐日的积雪深度、密度、积雪粒径、积雪硬度、积雪形态等数据。自动观测包括积雪深度、雪水当量、积雪反照率、液态水含量、积雪密度、风温湿压等要素。
\n6个超级站分别为阿勒泰站、天山雪崩站、甘德站、错那站、黑河站以及东北森林站。其中，每个超级站的自动观测和人工观测分别按年度存放于不同文件夹。其中，逐日人工观测数据存放于一个文件夹，包含环境照片、粒径照片、记录表格以及原始记录表扫描档。自动观测文件夹包含各观测仪器的表格、以及数据分析图。
\n数据集共包含28个文件夹、886个数据表，共974340条记录。数据集命名规则、时间范围及站点经纬度见说明文档。

The data integrity check mainly checks whether the time range and observation fields of the data at each station meet the project requirements. On the one hand, the data accuracy check determines and eliminates abnormal values through numerical illustration and manual experience. On the other hand, the data storage method and format are unified and standardized. The second stage is for different data providers to cross-check other data, review the integrity and accuracy of the data again, and integrate data from different regions.

Automatic observations include snow depth, snow water equivalent, snow albedo, liquid water content, snow density, wind temperature, pressure and other elements.
\r\nThe six super stations are Altay Station, Tianshan Avalanche Station, Gande Station, Cuona Station, Heihe Station and Northeast Forest Station. Among them, the automatic observations and manual observations of each super station are stored in different folders annually. Among them, daily manual observation data are stored in a folder, which contains environmental photos, particle size photos, record forms and scanned files of the original record form. The automatic observation folder contains tables and data analysis charts for each observation instrument.
