Meteosat Indian Ocean Sea Surface Temperature
Demonstrational Near real time productLevel 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 : MSG/SEVIRI
Other input : ECMWF outputs (temperature, humidity and aerosols profiles)
Temporal sampling : 24 per day
Timeliness :
?
The timeliness is the time elapsing from the sensing time of the last contributing file to the product dissemination to users. It is similar to the latency.
