观测项目有：空气温湿度（Ta_5m、RH_5m、Ta_10m、RH_10m）(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_5m、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_2cm、Ts_4cm、Ts_10cm、Ts_20cm、Ts_40cm）(单位：摄氏度)、冠层上向上与向下光合有效辐射（PAR_U_up、PAR_U_down）(单位：微摩尔/平方米秒)和冠层下向上与向下光合有效辐射（PAR_D_up、PAR_D_down）(单位：微摩尔/平方米秒)。
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：2019-6-10 10:30；（6）命名规则为：AWS+站点名称

This dataset contains meteorological element observation data from the Zhangye Wetland Station of the Heihe River Basin Surface Process Comprehensive Observation Network, covering the period from January 1, 2019 to December 31, 2018. The station is located at the National Wetland Park in Zhangye City, Gansu Province, with a reed wetland underlying surface. The coordinates of the observation point are 100.4464°E, 38.9751°N, and the elevation is 1460 m. Air temperature and relative humidity sensors are installed at 5 m and 10 m heights, facing due north; a barometer is installed at 2 m height; a tipping-bucket rain gauge is installed at 10 m height; wind speed sensors are installed at 5 m and 10 m heights, and the wind direction sensor is installed 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 probes pointing vertically downward; soil temperature probes are buried at 0 cm (surface) and 2 cm, 4 cm, 10 cm, 20 cm, 40 cm underground, 2 m south of the meteorological tower; three soil heat flux plates are buried at 6 cm underground; four photosynthetically active radiation (PAR) sensors are installed above and within the canopy: two are installed at 6 m height above the canopy (one probe pointing vertically upward, one downward), and two are installed at 0.25 m height within the canopy (one probe pointing vertically upward, one downward), all facing due south. Observation items include: air temperature and humidity (Ta_5m, RH_5m, Ta_10m, RH_10m) (units: degrees Celsius, percentage); atmospheric pressure (Press) (unit: hectopascal); precipitation (Rain) (unit: millimeter); wind speed (WS_5m, WS_10m) (unit: meters per second); wind direction (WD_10m) (unit: degree); 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_2cm, Ts_4cm, Ts_10cm, Ts_20cm, Ts_40cm) (unit: degrees Celsius); upward and downward PAR above the canopy (PAR_U_up, PAR_U_down) (unit: micromoles per square meter per second), and upward and downward PAR within the canopy (PAR_D_up, PAR_D_down) (unit: micromoles per square meter per second). Data processing and quality control: (1) Ensure 144 data points per day (one record every 10 minutes); missing data is marked with -6999; (2) Remove duplicate records at the same time; (3) Delete data that obviously exceeds physical limits or instrument measuring ranges; (4) Data marked in red are questionable; (5) The date and time formats are unified, and date and time are recorded in the same column, e.g., "2019-6-10 10:30"; (6) Naming convention: AWS+station name.
