North Atlantic Regional Sea Surface Temperature
Operational Near real time productLevel 3, four times a day, sub-skin Sea Surface Temperature derived from AVHRR on Metop and VIIRS on NOAA, over North Atlantic and European Seas and re-projected on a polar stereographic at 2 km resolution, in GHRSST compliant netCDF format.
Identification
Acronym : NAR SST
Product navigator reference :
EO:EUM:DAT:MULT:OSSTNARN
OSI SAF producer : Météo-France
Identifier : OSI-202-c
Digital object identifier (DOI) 10.15770/EUM_SAF_OSI_NRT_2012
Acronym for EDC (APNM) : OSSTNARN
Citation : See at bottom
Characteristics
Processing level : L3C
Satellite input : Metop-B/AVHRR and NOAA-20/VIIRS
Other input : ECMWF outputs (temperature, humidity and aerosols profiles)
Temporal sampling : 4 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.
6h
