Demonstrational Near real time product

Level 3 hourly sub-skin Sea Surface Temperature derived from Meteosat at 41.5° longitude, covering 60S-60N and 18.5W-101.5E and re-projected on a 0.05° regular grid, in GHRSST compliant netCDF format.

Identification
Acronym : MET IO SST
OSI SAF producer : Météo-France
Identifier : OSI-IO-SST
Citation : See at bottom
Characteristics
Processing level : L3C
Satellite input : Meteosat-9/SEVIRI
Other input : ECMWF outputs (temperature, humidity and aerosols profiles)
