The OSI SAF provides comprehensive information on the ocean-atmosphere interface — requirements of both meteorology and oceanography.
SAF Official Service Name
Satellite Application Facility on Ocean and Sea Ice (OSI SAF)
The OSI SAF is an answer to requirements, from the meteorological and oceanographic communities of EUMETSAT Member and Cooperating States, for comprehensive information derived from meteorological satellites at the ocean-atmosphere interface. The OSI SAF offers a precious complement to in-situ data, based on continuously increasing temporal and geographical resolution products from coastal to global coverage.
It takes into account, in particular, the requirements expressed in the framework of the World Meteorological Organization (WMO), Global Climate Observing System (GCOS), Group for High Resolution Sea Surface temperature (GHRSST), and finally, Copernicus and its Marine Environment Monitoring Service (CMEMS).

SAF input satellite data
The following satellite data sources are used to generate OSI SAF products:
- MSG (SEVIRI)
- GOES-E imager
- Metop (AVHRR, ASCAT, IASI)
- NOAA (AVHRR)
- DMSP (SSMR, SSM/I, SSMIS)
- Suomi NPP (VIIRS)
- ISS (RapidScat)
- GCOM (AMSR-2)
- Oceansat-2 (OSCAT)
- QuickSCAT (SeaWinds)
The OSI SAF develops, processes and distributes, in near real-time, products related to four key parameters of the ocean-atmosphere interface. Products are accessible on local FTP servers with flexible extraction interface, EUMETCast, and EUMETSAT Data Center(EDC). See the Product Navigator for detailed information on the OSI SAF products.
The OSI SAF also provides climatological datasets (such as Sea Ice concentration, winds, SST) accessible via the OSI SAF website.
SAF topology and architecture
R&D activities are shared among the consortium.
The production and associated services are based on 3 subsystems:
- Low and Mid latitude (LML) subsystem, under MF responsibility, processes and distributes the SST and Radiative Fluxes products covering LML, North Atlantic Regional (NAR) and Global areas. Ifremer contributes to the products distribution and archiving,
- High Latitude (HL) subsystem, under MET Norway responsibility with the co-operation of DMI, processes and distributes the Global Sea Ice products, the High Latitude SST and the High Latitude Radiative Fluxes,
- Wind subsystem, under KNMI responsibility, processes and distributes the Wind products.
SAF user community
Main usages of the OSI SAF products are: operational weather forecasting; operational marine meteorology; operational oceanography; polar research; research in meteorology and oceanography; climate monitoring, and environment monitoring.
