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；由于传感器问题，风速风向偶尔出现NAN无效值，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：2023-9-10 10:30；（6）命名规则为：AWS+站点名称。

This dataset contains meteorological element observation data from the Jingyangling Station, an upstream station of the Heihe River Basin Surface Process Comprehensive Observation Network, covering the period from January 1, 2023 to December 31, 2023. The station is located at the Jingyangling Pass in 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 a height of 5 m, facing due north; a barometer is installed in a tamper-proof box on the ground; a tipping-bucket rain gauge is installed at 10 m height; wind speed and direction sensors are mounted at 10 m height, facing due north; a four-component radiometer is installed at 6 m height, facing due south; two infrared thermometers are installed at 6 m height, facing due 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 due 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 due south of the meteorological tower. Three soil heat flux plates are sequentially buried at 6 cm underground, 2 m due south of the meteorological tower.

The observation items include: Air temperature and humidity (Ta_5m, RH_5m) (units: degrees Celsius, percentage); Barometric 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: degrees 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: degrees Celsius); Soil moisture (Ms_4cm, Ms_10cm, Ms_20cm, Ms_40cm, Ms_80cm, Ms_120cm, Ms_160cm) (unit: percentage).

Data processing and quality control procedures are as follows: (1) Ensure 144 data records per day (one record every 10 minutes). Missing data are marked with -6999; occasional invalid NaN values for wind speed and direction occur due to sensor malfunctions, and data for upward shortwave radiation from the four-component radiometer are erroneous. (2) Remove records with duplicate timestamps. (3) Delete data that significantly exceed physical thresholds or instrument measurement ranges. (4) Data portions marked in red indicate questionable values. (5) Date and time formats are unified, with date and time stored in the same column. For example, the time format is: 2023-9-10 10:30. (6) The file naming convention is: AWS + station name.
