Abstract Being simple and effective, the split-window algorithm based on thermal infrared remote sensing is widely used to retrieve surface temperature. The method mainly uses thermal infrared bands in 10~13.3 μm(1 000~750 cm-1) range, neglecting bands in 8~9.09 μm (1 250~1 100 cm-1) range. This paper analyzes the process of deriving the formula of the split-window algorithm, summarizes the problems associated with the channel setting and makes numerical simulation analysis in the 10~13.3 μm (1 000~750 cm-1) and 8~9.09 μm (1 250~1 100 cm-1) ranges to solve the problems. The results show that split-window algorithm derived on the basis of this approach has similar performance in both 10~13.3 μm (1 000~750 cm-1) and 8~9.09 μm (1 250~1 100 cm-1) spectral ranges. Therefore, it can be concluded that the spectral range in 8~9.09 μm (1 250~1 100 cm-1) range can also be used to derive split-window algorithm for thermal remote sensing.
