该数据集包含了2020年1月1日至2020年12月31日黑河流域地表过程综合观测网上游景阳岭站气象要素观测数据。站点位于青海省祁连县景阳岭垭口，下垫面是高寒草甸。观测点的经纬度是101.1160E, 37.8384N，海拔3750m。空气温度、相对湿度传感器架设在5m处，朝向正北；气压计安装在地面上的防撬箱内；翻斗式雨量计安装在10m处；风速与风向传感器架设在10m，朝向正北；四分量辐射仪安装在6m处，朝向正南；两个红外温度计安装在6m处，朝向正南，探头朝向是垂直向下；土壤温度探头埋设在地表0cm和地下4cm、10cm、20cm、40cm、80cm、120cm、160cm处，在距离气象塔2m的正南方；土壤水分探头埋设在地下4cm、10cm、20cm、40cm、80cm、120cm、160cm处，在距离气象塔2m的正南方；土壤热流板（3块）依次埋设在地下6cm处，在距离气象塔2m的正南方。
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3.14-4.25间数据缺失；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：2020-9-10 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, 2020 to December 31, 2020. The station is located at the Jingyangling Pass in Qilian County, Qinghai Province, with an alpine meadow 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 installed at 5 m height, facing due north; the barometer is installed in a tamper-proof box on the ground; the tipping-bucket rain gauge is installed at 10 m height; wind speed and direction sensors are installed at 10 m height, facing due north; the 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 depths of 4 cm, 10 cm, 20 cm, 40 cm, 80 cm, 120 cm, and 160 cm below the surface, 2 m directly south of the meteorological tower; soil moisture probes are buried at depths of 4 cm, 10 cm, 20 cm, 40 cm, 80 cm, 120 cm, and 160 cm below the surface, 2 m directly south of the meteorological tower; three soil heat flux plates are sequentially buried at 6 cm below the surface, 2 m directly south of the meteorological tower. 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: (1) Ensure 144 data records per day (one record every 10 minutes); missing data is marked with -6999. Data from March 14 to April 25 are missing due to insufficient power supply caused by snow covering the solar panels; occasional NAN invalid values for wind speed and direction and erroneous data for upward shortwave radiation of the four-component set are caused by sensor issues. (2) Remove duplicate records at the same timestamp; (3) Delete data that obviously exceed physical limits or instrument measurement ranges; (4) Data marked in red are questionable; (5) The date and time formats are unified, and date and time are stored in the same column. For example, the time format is: 2020-9-10 10:30; (6) The naming convention is: AWS + station name.

(2018), and data processing procedures for the observations can be referred to in Liu et al. (2011).
