Abstract

Accurate representation of land surface temperature (LST) at a large-scale is of great concern in numerous environmental studies. Simply averaging of LST measured at a small-scale into the large-scale may lead to misrepresentation due to spatial variability in LST and uncertainty in surface heterogeneity. The satellite-derived LST may be more comprehensive in large-scale observation, yet it often has the satellite-view biases, which is especially true to terrain area. To account for these factors, an approach for LST scaling was proposed, based on the Stefan-Boltzmann law and terrain correction approach used in remote sensing. It was further modified oriented to satellite-derived LST. A terrain area over the Loss Plateau of China was selected for examination. The Lipton-Ward (L-W) approach, which was originally developed for addressing the satellite-view biases in retrieved LST in mountain area, was also adopted in the examination from the perspective of scaling. Incorporated with 90-m topographical data, 90-m LST and emissivity products from The Advanced Spaceborne Thermal Emission Reflection Radiometer (ASTER) were scaled up to 900-m using the two approaches. Results showed that the proposed approach smoothed the LST difference and reduced the standard deviation of LST but the L-W approach did not. This was further confirmed from the comparison with the terrain corrected 900-m LST, which was produced from the LST products of The MODerate resolution Imaging Spectroradiometer (MODIS) onboard the same satellite platform with ASTER sensor.
