On automatic cloud detection over ocean
An automatic cloud classification algorithm is proposed for the Advanced Very High Resolution Radiometer (AVHRR), based on a 5-D histogram technique. The technique determines three-level (high, medium, low) cloud amount and the average cloud-top brightness temperature (BT) and reflectance for 128×128 pixel areas. Comparison of the products for NOAA-11 AVHRR measurements during 14 orbits over oceans with the International Satellite Cloud Classification Project DX products for the same AVHRR data set is presented.
