Estimation of the Surface Thermal Transfer Coefficients over the Arid Region of Northwest China with the Aid of Satellite Remote Sensing and Field Observations

The surface thermal transfer coefficients (CH) of different underlying surfaces over the arid region of Northwest China are calculated using the air dynamics method with the Heihe field experiment (HEIFE) observations, and theCH-NDVI parametric relational expressions are obtained by fitting method with the aid of the normalized difference vegetation index (NDVI) data observed by the National Oceanic and Atmospheric Administration (NOAA) remote sensing satellites, and then the authors make the reasonableness test to them. The results show that estimation of the surface thermal transfer coefficients with the aid of satellite remote sensing and field observations is a credible way under the circumstances of the absence of other accurate methods.
