The Research of Split-Window Algorithm on the MODIS

In this paper, the authors introduce the theory base of split-window algorithm and make a derivation for the split-window algorithm. As to the characters of the MODIS bands, the authors make a simplification for the Planck function. For the two main parameters of the split algorithm, the authors obtain them from the same image. Finally the authors retrieve the LST of Huanbohai region by using MODIS data and get the spatial distribution of LST in this region and make some analysis for the retrieval results.
