OPERATIONAL SST RETRIEVAL FROM METOP/AVHRR
The new EUMETSAT Polar Orbiter, METOP, carries an Advanced Very High Resolution Radiometer (AVHRR) that enables the retrieval of Sea Surface Temperature (SST) over the world ocean. The Ocean and Sea Ice Satellite Application Facility (OSI SAF) of EUMETSAT has developed an operational processing chai...
