Paper Abstract

An algorithm for retrieving land surface temperature (LST) was developed by using multiple linear regression analysis and path analysis based on the National Oceanic and Atmospheric Administration's Advanced Very High Resolution Radiometer (AVHRR) remotely sensed thermal infrared data. The analysis results indicated that the brightness temperatures of the AVHRR thermal infrared channels 4 and 5 should be involved in retrieving LST, and showed that it became difficult to disentangle the effects of the brightness temperatures of the AVHRR channels 4 and 5 on LST. Therefore, a split-window algorithm for retrieving LST was developed by introducing the difference of the two brightness temperatures.
