The data set contains the meteorological element observation data of bajitan Gobi station in the middle reaches of Heihe hydrometeorological observation network from September 21, 2012 to December 31, 2013. The station is located in bajitan in the west of Zhangye City, Gansu Province, and the underlying surface is Gobi. The longitude and latitude of the observation point are 100.3042e, 38.9150n and 1562m above sea level

  The air temperature and relative humidity sensors are erected at 5M and 10m, facing due north; The barometer is installed at 2m; Tipping bucket rain gauge shall be installed at 10m; The wind speed sensor is erected at 5M and 10m, and the wind 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 2cm, 4cm, 10cm, 20cm, 40cm, 60cm and 100cm underground, just south of the meteorological tower 2m away; Soil moisture sensors are buried 2cm, 4cm, 10cm, 20cm, 40cm, 60cm and 100cm underground, just south of the meteorological tower 2m away; Soil heat flow plates (3 pieces) are successively buried 6cm underground. Observation items are:

  Air temperature and humidity (TA)_ 5m、RH_ 5m、Ta_ 10m、RH_ 10m (in degrees Celsius, percentage), pressure (press) (in HPA), precipitation (rain) (in mm), wind speed (WS)_ 5m、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) (unit: watt / m2), soil moisture (MS)_ 2cm、Ms_ 4cm、Ms_ 10cm、Ms_ 20cm、Ms_ 40cm、Ms_ 60cm、Ms_ 100cm) (unit: volume water content, percentage) and soil temperature (TS)_ 0cm、Ts_ 2cm、Ts_ 4cm、Ts_ 10cm、Ts_ 20cm、Ts_ 40cm、Ts_ 60cm、Ts_ 100cm) (in degrees Celsius)

  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

 （ 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, June 10, 2013

 （ 6) The naming rule is: AWS + site name
