Paper Abstract
Twenty-six daytime NOAA-11/AVHRR images covering the Danish waters are analyzed together with 99 cloud-free bulk temperature measurements. The images are cloud screened with a cloud-detection algorithm, which among other tests is based on a correlation test between channels 2, 4, and 4-5. This correlation test is capable of distinguishing cold water pixels from cloud pixels. According to the split-window hypothesis, the channel 4-5 brightness temperatures should increase, and the channel 4 brightness temperatures should decrease with the radiation path. These split-window assumptions are examined, and the channel 4-5 difference does not seem to carry significant information about the true sea surface temperature.
