Quality of satellite imagery is affected by cirrus clouds, which are often overlooked in the prescreening process. Some image processing techniques have been used to remove the thin cloud effect, but their applicability is limmited because of lack of physical background. In this paper, we note the fact that the cirrus clouds are located in upper cold atmosphere, and propose a correction method based on the assumption that the digital numbers in visible bands increase in propotion to the difference from surface temprerature. It is shown that the method works well for an actual Landsat TM image after some parameter fitting.
