Abstract :
Clouds were detected from NOAA/AVHRR channel 4 data received at Syowa Station in the Antarctic. First, the surface temperature of each pixel in the area was calculated. Then, these values were used as thresholds that were applied to each position. Thirty daily scenes received at daytime in November 1988 were analyzed. Almost all clouds could be detected correctly in these scenes
