Abstract :
The AVHRR (Advanced Very High Resolution Radiometer) data on NOAA satellite have been mainly used to detect the sea surface temperature. AVHRR have relatively high spatial resolution, while had a fault which cannot observe sea surface temperature under cloudy condition. The AMSR-E (Advanced Microwave Scanning Radiometer for EOS) sensor launched in 2002 solved this fault. Since the sensor detects using the GHz band, the sensor detects the sea surface temperature under cloudy condition. In this paper, a program based on an optical flow method is developed to process the AMSR-E data to detect mesoscale surface flow.
