Agricultural irrigation, which accounts for about 80% of human water consumption, is the most important part of human water resources management and closely related to human survival and development.Irrigation is also an important part of the water cycle. Large-scale irrigation can affect the water cycle and even the local climate by affecting evapotranspiration.Excessive diversion of irrigation water will lead to unsustainable utilization of water resources, and at the same time, will reduce river flow and aquifer water reserves, thus harming the ecological environment. Therefore, determining the spatial and temporal distribution and variation of irrigation is critical to studying past human water use, the impact of irrigation on ecological and hydrological processes, the environment and climate, and the development of future irrigation plans. By integrating the irrigation amount of channel diversion water and irrigation amount of groundwater intake from different data sources, and combining the evapotranspiration data of land surface model CLM4.5 simulation and remote sensing inversion, a set of spatio-temporal continuous surface water and groundwater irrigation amount data set with spatial resolution of 30 arcseconds (0.0083 degrees) on the scale of 1981-2013 in heihe river basin was made. It has been verified that this data set has a high reliability from 2000 to 2013, and a lower reliability from 1981 to 1999 than from 2000 to 2013 due to the absence of remote sensing data and the absence of soil utilization changes. The document is described as follows: Monthly surfacewater irrigation volume file name: monthly_surfacewater_irrigation gation_1981-2013.nc Monthly groundwater_irrigation gation_1981-2013.nc The data is in netcdf format.There are three dimensions, which are month, lat, and lon. Where, month is a month, and the value is 0-395, representing each month from 1981 to 2013. Lat is grid latitude information, and lon is grid longitude information.

In order to monitor changes in the groundwater level and in the groundwater temperature in the cold region hydrology experiment area, six sets of instruments (the HOBO pressure type mario/thermograph: U20-001-01; U20-001-01-TI) were scattered by Cold and Arid Regions Environmental and Engineering Research Institute, CAS in the Yingke oasis, Xinmiao village in Daman township, Daman Water Management office, Wangqizha village in Xiaoman township, Yanhe village in Mingyong county, Xiaowan village in Wujiang township and Liuquan village in Xindun township respectively. The items were mainly the groundwater pressure and the groundwater temperature . Based on the air pressure obtained in the Yingke oasis station, the groundwater pressure by HOBO could be changed into the grounwater depth, and the groundwater level could be developed by differential GPS.
