AB  - The data set contains the observation data of automatic weather station at point 20 in the flux observation matrix from June 2 to September 21, 2012. The station is huazhaizi station in Zhangye City, Gansu Province, with desert on the underlying surface. The longitude and latitude of the observation point are 100.31860e, 38.76519n and 1731.00m above sea level. Two infrared surface temperature sensors are installed at 2.65m, with the arm facing due south and the probe facing vertically downward; The soil temperature probe is buried at 0cm on the surface and 2cm and 4cm underground, and is 2m away from the south of the meteorological tower; The soil moisture sensor is buried 2cm and 4cm underground, and is 2 meters south of the meteorological tower; Soil heat flow plates (3 pieces) are successively buried 6 cm underground. The data sets of the station are stored in two tables. The time interval of the observation data sets of Beijing Normal University is 10 minutes on average, and the time interval of the observation data sets of the Institute of cold and drought of Chinese Academy of Sciences is 30 minutes on average. The specific observation elements are as follows:（ 1) Observation items: surface radiation temperature (IRT)_ 1、IRT_ 2) (unit: Celsius, percentage), soil heat flux (GS)_ 1、Gs_ 2、Gs_ 3) (unit: watt / m2), multi-layer soil moisture (MS)_ 2cm、Ms_ 4cm (in percentage) and multi-layer soil temperature (TS)_ 0cm、Ts_ 2cm 、Ts_ 4cm) (in degrees Celsius).（ 2) The observation items of cold and drought Institute of huazhaizi Chinese Academy of sciences include: wind speed (WS_ 0.48m、WS_ 0.98m、WS_ 1.99m、WS_ 2.99m (unit: M / s), wind direction (WD)_ 4m (in degrees), dust concentration (funjin)_ mgm3_ AVG), four components of radiation (DR, ur, DLR)_ Cor、ULR_ COR, RN (unit: w / m2), air temperature and humidity observation (TA)_ 1m  、Ta_ 1.99m、Ta_ 2.99m、RH_ 1m、RH_ 1.99m、RH_ 2.99m (unit: Celsius, percentage), pressure (press) (unit: HPA), multi-layer soil temperature (T
