观测项目有：空气温湿度（Ta_5m、RH_5m）(单位：摄氏度、百分比)、气压（Press）(单位：百帕)、降水量（Rain）(单位：毫米)、风速（WS_10m）(单位：米/秒)、风向（WD_10m）(单位：度)、四分量辐射（DR、UR、DLR_Cor、ULR_Cor、Rn）(单位：瓦/平方米)、地表辐射温度（IRT_1、IRT_2）(单位：摄氏度)、土壤热通量（Gs_1、Gs_2、Gs_3）(单位：瓦/平方米)、土壤温度（Ts_0cm、Ts_4cm、Ts_10cm、Ts_20cm、Ts_40cm、Ts_80cm、Ts_120cm、Ts_160cm）(单位：摄氏度)、土壤水分（Ms_4cm、Ms_10cm、Ms_20cm、Ms_40cm、Ms_80cm、Ms_120cm、Ms_160cm）(单位：百分比)。
观测数据的处理与质量控制：（1）确保每天144个数据（每10min），若出现数据的缺失，则由-6999标示；（2）剔除有重复记录的时刻；（3）删除了明显超出物理意义或超出仪器量程的数据；（4）数据中以红字标示的部分为有疑问的数据；（5）日期和时间的格式统一，并且日期、时间在同一列。如，时间为：2015-9-10 10:30；（6）命名规则为：AWS+站点名称。

This dataset contains meteorological element observation data from the Jingyangling Station in the upper reaches of the Heihe River Hydrometeorological Observation Network, covering the period from January 1, 2015 to December 31, 2015. The station is located at Jingyangling Pass, Qilian County, Qinghai Province, with an alpine meadow as its underlying surface. The geographic coordinates of the observation site are 101.1160°E, 37.8384°N, and the elevation is 3750 m.

Air temperature and relative humidity sensors are mounted at 5 m, facing true north; the barometer is installed in an anti-pry enclosure on the ground; the tipping-bucket rain gauge is installed at 10 m; wind speed and direction sensors are mounted at 10 m, facing true north; the four-component radiometer is installed at 6 m, facing true south; two infrared thermometers are installed at 6 m, facing true south, with their probes pointing vertically downward.

Soil temperature probes are buried at 0 cm (surface) and 4 cm, 10 cm, 20 cm, 40 cm, 80 cm, 120 cm, 160 cm underground, 2 m directly south of the meteorological tower. Soil moisture probes are buried at 4 cm, 10 cm, 20 cm, 40 cm, 80 cm, 120 cm, 160 cm underground, 2 m directly south of the meteorological tower. Three soil heat flux plates are sequentially buried at 6 cm underground, 2 m directly south of the meteorological tower.

Observation items include: air temperature and humidity (Ta_5m, RH_5m) (units: degree Celsius, percentage), atmospheric pressure (Press) (unit: hectopascal), precipitation (Rain) (unit: millimeter), wind speed (WS_10m) (unit: meter per second), wind direction (WD_10m) (unit: degree), four-component radiation (DR, UR, DLR_Cor, ULR_Cor, Rn) (unit: watt per square meter), surface radiation temperature (IRT_1, IRT_2) (unit: degree Celsius), soil heat flux (Gs_1, Gs_2, Gs_3) (unit: watt per square meter), soil temperature (Ts_0cm, Ts_4cm, Ts_10cm, Ts_20cm, Ts_40cm, Ts_80cm, Ts_120cm, Ts_160cm) (unit: degree Celsius), soil moisture (Ms_4cm, Ms_10cm, Ms_20cm, Ms_40cm, Ms_80cm, Ms_120cm, Ms_160cm) (unit: percentage).

Data processing and quality control: (1) Ensure 144 data records per day (one record every 10 minutes); missing data are marked with -6999; (2) Remove duplicate records at the same time stamp; (3) Delete data that obviously exceed physical limits or instrument measurement ranges; (4) Data marked in red indicate questionable values; (5) The formats of date and time are unified, and date and time are stored in the same column. For example, the time format is: 2015-9-10 10:30; (6) The naming convention is: AWS + station name.
