该数据集包含了大冬树山垭口积雪观测站的自动气象站观测数据，站点位于青海省祁连县南部地区。观测点的经纬度为100°14′E，38°01′N，海拔高度为4101m。观测场建在黑河上游大冬树山垭口东侧的高地上，试验场周围地势相对平坦开阔，自东南向西北略有倾斜下降。大冬树山垭口的地表由高寒草甸和块石构成，秋、冬、春季常被积雪覆盖，是一个比较理想的积雪观测站。
\n该站点是典型高山寒漠景观，观测项目有：大气风温湿梯度观测（2m和10m）、气压、雨雪量计、雪深、辐射四分量、多层土壤温度（5cm、10cm、20cm、40cm、80cm和120cm）、土壤水分（5cm、10cm、20cm、40cm、80cm和120cm）及土壤热通量（5cm和15cm）。
\n原始的采集器输出数据为0级；初步整理后，没有任何的删除，但是标出疑似有问题的数据为1级；统一整理成30分钟采样周期并经过质量控制的为2级。整理后的数据逐月存储，命名规则为：站点名+数据级别+AMS+数据日期。建议普通用户用2级以上的数据。
\n数据观测时段为2007年10月29日至2009年10月1号。由于此站点的安全维护问题，数据缺失比较严重。详细信息请请参见[http://westdc.westgis.ac.cn/doc/ 气象水文通量数据使用指南.pdf 气象水文通量数据使用指南]。

The data set contains the automatic weather station observation data of dadongshushan Yakou snow observation station, which is located in the south of Qilian County, Qinghai Province. The longitude and latitude of the observation point are 100 ° 14 ′ e, 38 ° 01 ′ n, and the altitude is 4101m. The observation site is built on the highland in the east of dadongshushan pass in the upper reaches of Heihe River. The terrain around the test site is relatively flat and open, with a slight inclination from southeast to northwest. The surface of dadongshushan pass is composed of alpine meadow and block stone. It is often covered with snow in autumn, winter and spring. It is an ideal snow observation station.\n
