HiWATER: Simultaneous observation dataset of land surface temperature in the lower of Heihe River Basin on Aug. 01, 2014

The aim of the simultaneous observation of land surface temperature is obtaining the land surface temperature for different kinds of underlying surface, including the lager areas of homogeneous vegetation with high coverage, water, and concrete floor, while the thermal imager go into the experimental areas of the low reaches. All the land surface temperature data will be used for validation of the retrieved land surface temperature from thermal imager and the analysis of the scale effect of the land surface temperature, and finally serve for the validation of the plausibility checks of the surface temperature product from remote sensing.

1. Observation time

On 1 August, 2014

2. Observation samples

Three field samples were chosen in the fly zone, which were large areas of homogeneous vegetation (with high coverage), water, and concrete floor.

3. Observation method

Surface temperature values were observed continuously for each sample using handheld infrared thermometers during the imager went into the flying area.

4. Instrument parameters and calibration

The field of view of the handheld infrared thermometer is one degree and the emissivity was assumed to be 0.95. All instruments were calibrated on 31 July, 2014 using a black body.

5. Data storage

All the observation data were stored in an excel.
