Data of meteorological stations in the middle reaches of Heihe hydrometeorological observation network
The air temperature and relative humidity sensors are erected at 5m, facing due north; The barometer is installed in the skid proof box on the ground; Tipping bucket rain gauge shall be installed at 10m; The wind speed and direction sensor is erected at 10m, facing due north; The four component radiometer is installed at 6m, facing due south; Two infrared thermometers are installed at 6m, facing due south, and the probe is vertically downward; The soil temperature probe is buried at 0cm on the surface and 4cm, 10cm, 20cm, 40cm, 80cm, 120cm and 160cm underground, just south of the meteorological tower 2m away; The soil moisture probe is buried at 4cm, 10cm, 20cm, 40cm, 80cm, 120cm and 160cm underground, just south of the meteorological tower 2m away; Soil heat flow plates (3 pieces) are successively buried 6cm underground, 2m south of the meteorological tower
Observation items: air temperature and humidity (TA)_ 5m、RH_ 5m (in degrees Celsius, percentage), pressure (press) (in HPA), precipitation (rain) (in mm), wind speed (WS_ 10m (unit: M / s), wind direction (WD)_ 10m (in degrees), four component radiation (DR, ur, DLR)_ Cor、ULR_ COR, RN (unit: w / m2), surface radiation temperature (IRT)_ 1、IRT_ 2) (unit: Celsius), soil heat flux (GS)_ 1、Gs_ 2、Gs_ 3) (in watts per square meter), soil temperature (TS)_ 0cm、Ts_ 4cm、Ts_ 10cm、Ts_ 20cm、Ts_ 40cm、Ts_ 80cm、Ts_ 120cm、Ts_ 160cm (in degrees Celsius), soil moisture (MS)_ 4cm、Ms_ 10cm、Ms_ 20cm、Ms_ 40cm、Ms_ 80cm、Ms_ 120cm、Ms_ 160cm) (in percentage)
Observation data processing and quality control:
（ 1) Ensure 144 data every day (every 10min). In case of missing data, it shall be marked by - 6999; The four component radiation is between June 12 and June 30, 2014. Due to the problem of collector expansion board, the data is missing; The soil temperature is between June 12 and June 14, 2014. Due to the problem of data collector, the data is missing; 7.22-8.19 the wind speed is missing due to the problem of the sensor; The surface radiation temperature is between 9.2-10.23, and the data is missing due to the problem of collector expansion board
（ 2) Eliminate the time with duplicate records
（ 3) Data that is obviously beyond the physical meaning or beyond the range of the instrument are deleted
（ 4) The part marked in red in the data is questionable data
（ 5) The format of date and time is unified, and the date and time are in the same column. For example, the time is: 10:30, September 10, 2014
（ 6) The naming rule is: AWS + site name
Good data quality
