This dataset includes data recorded by the Cold and Arid Research Network of Lanzhou university obtained from an observation system of Meteorological elements gradient of Suganhu Station from November 27 to December 31, 2019. The site (94.12 E, 38.99 N) was located on a wetland in the Suganhu west lake, Gansu Province. The elevation is 2823 m. The installation heights and orientations of different sensors and measured quantities were as follows: air temperature and humidity profile (4m and 8 m, towards north), wind speed and direction profile (windsonic; 4m and 8 m, towards north), air pressure (1 m), rain gauge (4 m), infrared temperature sensors (4 m, towards south, vertically downward), soil heat flux (-0.05 and -0.1m ), soil soil temperature/ moisture/ electrical conductivity profile (below the vegetation in the south of tower, -0.1, -0.2 and -0.4m), photosynthetically active radiation (4 m, towards south), four-component radiometer (4 m, towards south), sunshine duration sensor(4 m, towards south). The observations included the following: air temperature and humidity (Ta_4 m, Ta_8 m; RH_4 m, RH_8 m) (℃ and %, respectively), wind speed (Ws_4 m, Ws_8 m) (m/s), wind direction (WD_4 m, WD_8 m) (°), air pressure (press) (hpa), precipitation (rain) (mm), four-component radiation (DR, incoming shortwave radiation; UR, outgoing shortwave radiation; DLR_Cor, incoming longwave radiation; ULR_Cor, outgoing longwave radiation; Rn, net radiation) (W/m^2), infrared temperature (IRT) (℃), photosynthetically active radiation (PAR) (μmol/ (s m-2)), soil heat flux (Gs_0.05m, Gs_0.1m) (W/m^2), soil temperature (Ts_0.1m, Ts_0.2m, Ts_0.4m) (℃), soil moisture (Ms_0.1m, Ms_0.2m, Ms_0.4m) (%, volumetric water content), soil conductivity (Ec_0.1m, Ec_0.2m, Ec_0.4m)(μs/cm), sun time(h). The data processing and quality control steps were as follows: (1) The AWS data were averaged over intervals of 10 min for a total of 144 records per day. The 40cm soil water potential data were rejected because of sensor error. (2) Data in duplicate records were rejected. (3) Unphysical data were rejected. (4) The data marked in red are problematic data. (5) The format of the date and time was unified, and the date and time were collected in the same column, for example, date and time: 2019-6-10 10:30.

Five different altitude zones were selected for this test. Their altitude, latitude and longitude are 3650 meters above sea level, latitude and longitude 99°55'24 E, 38°24'60" N; altitude of 3550 meters, latitude and longitude 99°55'28 E, 38°25'11" N; 3450 meters above sea level, longitude and latitude 99°55'38 E, 38°25'68" N; 3350 meters above sea level, longitude and latitude 99°55'37 E, 38°25'11" N; 3050 meters above sea level, longitude and latitude 99°55'42 E, 38°25'54" N. From May 31 to August 31, 2011, in the case of natural rainfall, the total rainfall was measured once every ten days using a rain gauge on five samples. To compare the difference in rainfall at different altitudes, it is necessary to combine the rainfall data observed by the project at the grassland weather station in 2011.

The annual report (2008 and 2009) of the Zhangye water conservancy bureau included: (1) the water management staff statistics; (2) irrigation statistics; (3) projects status statistics; (4) project management statistics; (5) the technical and economic index of the irrigation area management; (6) water management tasks status statistics; (7) water management planning index. Those provide reliable information for water resources analysis in the middle stream.
Zhangye Water Conservancy Bureau,
This dataset contains SMAP time-expanded daily 0.25°×0.25° land surface soil moisture products in Qilian Mountain Area from June 19, 2002 to Dec 31, 2021. The dataset was produced based on Random Forest method by utilizing AMSR-E and AMSR2 brightness temperature from 6.925 GHz V/H, 10.65 GHz V/H and 36.5 GHz V channels along with some auxiliary datasets. The auxiliary datasets participating in the RF training include IGBP land cover type, GTOPO30 DEM and Lat/Lon information.
