HiWATER: Simultaneous Observation Dataset of River Surface Temperature in the middle reaches of the Heihe River Basin on 3 July and 4 July, 2012

The aim of the simultaneous observation of river surface temperature is obtaining the river surface temperature of different places, while the sensor of thermal infrared go into the experimental areas of artificial oases eco-hydrology on the middle stream. All the river surface temperature data will be used for validation of the retrieved river surface temperature from thermal infrared sensor and ...

HiWATER: Simultaneous Observation Dataset of Land Surface Temperature in the middle reaches of the Heihe River Basin

The aim of the simultaneous observation of land surface temperature is obtaining the land surface temperature of different kinds of underlying surface, including greenhouse film, the roof, road, ditch, concrete floor and so on, while the sensor of thermal infrared go into the experimental areas of artificial oases eco-hydrology on the middle stream. All the land surface temperature data will be us...
