%X <pre><code> This data set contains the analysis data of chemical properties of snow samples from 6 Super stations in typical snow areas in China in 2017-2020, 6 lines in 2017-2019 and 2020-2021. Chemical properties include black carbon concentration, pH value, main cation and anion and conductivity. Snow depth is used as auxiliary information. Ordinary stations are mainly located in Xinjiang, Qinghai, Tibet, Inner Mongolia and Northeast China. Among them, ordinary stations in Xinjiang, Qinghai, Inner Mongolia and Northeast China contain snow depth and air temperature data, and ordinary stations in Tibet contain snow depth and snow pressure data. The super stations are 1_ Altay station, 2_ Tianshan avalanche station, 3_ Gande station, 4_ Wrong station, 5_ Heihe station and 6_ Northeast forest station. The observation lines mainly include line 1 - snow area north of Tianshan Mountain in Xinjiang, line 2 - snow area south of Tianshan Mountain in Xinjiang, line 3 - snow area in the Middle East of Qinghai Tibet Plateau, line 4 - snow area in the south of Qinghai Tibet Plateau, line 5 - Inner Mongolia northeast snow area, and line 6 - snow area around Changbai Mountain and Xiaoxing'an Mountain in the northeast. Among them, the sampling data of super station and observation line are stored in one folder respectively. Each folder contains the current year data table and data analysis diagram of each super station or line. The data set naming rules, time range and station longitude, latitude and altitude information are shown in the description document.
