AB  - During the Heihe integrated remote sensing joint test, in order to monitor the changes of groundwater level and water temperature in the arid area of the middle reaches, the cold and drought Institute of the Chinese Academy of Sciences deployed 6 sets of groundwater observation equipment in Yingke oasis in the hydrological test area of the arid area of the middle reaches. The observation points are: 1) Xinmiao village, Daman town (Xinmiao village, former Heping township); 2) Large full water pipe station; 3) Wangqizha village, Xiaoman town; 4) Group 1, Yanhe village, Mingyong township (Report No. 5); 5) Xiaowan village, Wujiang town; 6) Liuquan village, Xindun town. Observation instrument: hobo pressure type water level temperature recorder (model: u20-001-01); U20-001-01-TI）。 Observation frequency: 1 hour (December 25, 2007 ~ July 6, 2009). The observation items are the pressure at the sensor of the water level gauge (the groundwater level can be calculated) and the water temperature. The data set was observed from December 25, 2007 to July 6, 2009. Combined with the atmospheric pressure data observed by oasis station in Yingke irrigation area, the pressure data measured by hobo water level and temperature recorder can be transformed into water depth data through calculation. The buried depth of water level is obtained by using the length of water level gauge cable.The elevation of groundwater well is accurately measured by differential GPS, and the water level elevation is obtained by subtracting the water depth and buried depth
