This data set includes Yingke / da man irrigation 5.5km in the middle reaches of Heihe River × Continuous observation data of 50 waternet nodes in the 5.5km observation matrix from May to December 2012 (10 nodes are observed in December and the rest are observed in September). All 50 nodes contain 4cm and 10cm two-layer hydro probe II probes to observe the main variables such as soil moisture, soil temperature, conductivity and complex dielectric constant; Among them, 29 nodes are equipped with si-111 infrared temperature probe at the height of 4m to observe the surface radiation infrared temperature of the underlying surface, and the other node is equipped with si-111 infrared temperature probe at the height of 4m to cooperate with Daman super station to observe the atmospheric infrared radiation temperature. It can provide spatiotemporal continuous observation data sets for remote sensing estimation and remote sensing authenticity test of key hydrothermal variables on heterogeneous surface, ecological hydrology research, irrigation optimization management and so on.
All 50 nodes contain 4cm and 10cm two-layer hydro probe II probes to observe soil moisture, soil temperature, conductivity and complex dielectric constant.
The time and frequency of routine observation is 10 minutes. In order to ensure the accurate synchronization between si-111 and remote sensing, 1 minute encrypted observation is carried out every day at 00:00-04:30, 08:00-18:00 and 21:00-24:00.
Good data quality
