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；由于雪覆盖太阳能板引起供电不足，导致2.3-3.18间数据缺失；由于传感器问题，6.6-6.20、6.22-7.30风速风向出现较多NAN无效值，9-10月四分量向上短波辐射数据出错。（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：2019-9-10 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 Basin Surface Process Comprehensive Observation Network, covering the period from January 1, 2019 to December 31, 2019.
The station is located at the Jingyangling Pass, Qilian County, Qinghai Province, with an alpine meadow underlying surface. The observation site has geographic coordinates of 101.1160°E, 37.8384°N, and an elevation of 3750 m.
Air temperature and relative humidity sensors were mounted at 5 m height, facing true north; the barometer was installed in an anti-theft enclosure on the ground; the tipping-bucket rain gauge was installed at 10 m height; wind speed and direction sensors were mounted at 10 m height, facing true north; the four-component radiometer was installed at 6 m height, facing true south; two infrared thermometers were installed at 6 m height, facing true south, with their probes pointing vertically downward; soil temperature probes were 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 were 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 were 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: degrees Celsius, percent), barometric pressure (Press) (unit: hectopascals), precipitation (Rain) (unit: millimeters), wind speed (WS_10m) (unit: meters per second), wind direction (WD_10m) (unit: degrees), four-component radiation (DR, UR, DLR_Cor, ULR_Cor, Rn) (unit: watts per square meter), surface radiation temperature (IRT_1, IRT_2) (unit: degrees Celsius), soil heat flux (Gs_1, Gs_2, Gs_3) (unit: watts per square meter), soil temperature (Ts_0cm, Ts_4cm, Ts_10cm, Ts_20cm, Ts_40cm, Ts_80cm, Ts_120cm, Ts_160cm) (unit: degrees Celsius), soil moisture (Ms_4cm, Ms_10cm, Ms_20cm, Ms_40cm, Ms_80cm, Ms_120cm, Ms_160cm) (unit: percent).
Observation data processing and quality control: (1) Ensure 144 data points per day (collected every 10 minutes); missing data is marked with -6999. Data between February 3 and March 18 was missing due to insufficient power supply caused by snow covering the solar panels. Due to sensor issues, numerous NAN invalid values appeared in wind speed and direction data between June 6 and June 20, and between June 22 and July 30; data for upward shortwave radiation from the four-component radiometer was erroneous between September and October. (2) Remove records with duplicate timestamps. (3) Delete data that clearly exceeds physical plausibility or instrument measurement ranges. (4) Portions marked in red in the dataset are considered questionable data. (5) Uniform date and time format is used, with date and time in the same column. For example, the timestamp format is: 2019-9-10 10:30. (6) The naming convention is AWS+station name.
