Based on detailed studies of quite a few NOAA/AVHRR images, it is found that the image of channel 3 could be used to extract not only the information of high temperature objects but the information of normal temperature objects as well, and that in many cases it is better than the image of channel 4 in the information extraction. In this paper the authors have also made a concrete analysis and probed into the causes of such a phenomenon.
