SST in Polynias - a case study

Sea surface temperatures (SSTs) in Antarctic polynias are observed with NOAA-7 imagery. The study demonstrates the possibility of separating open water areas from clouds and ice with Advanced Very High Resolution Radiometer (AVHRR) channels 1, 3, 4 and 5 accurately enough for surface-temperature ret...
