Ocean and Sea Ice

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)

SAF Objectives

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 0° and over Indian Ocean (SEVIRI), then MTG (FCI)
  • GOES-East (ABI)
  • Metop (AVHRR, ASCAT, IASI), then Metop-SG (METimage, MWI, SCA, IASI-NG)
  • ScatSat (OSCAT)
  • ISS (RapidScat)
  • GCOM-W (AMSR-2)
  • Oceansat-2 (OSCAT)
  • QuickSCAT (SeaWinds)
  • ERS (SCAT) 

SAF products

The OSI SAF develops, processes and distributes, in near real-time, products related to four key parameters of the ocean-atmosphere interface: wind vectors, sea and sea ice surface temperature, radiative fluxes and sea ice. These near real-time products are accessible through the OSI SAF FTP servers with flexible extraction interface, EUMETCast, and EUMETSAT Data Center (EDC).

The OSI SAF also develops, processes and distributes Climate Data Records (Sea ice, winds, sea surface temperature) that are available on OSI SAF FTP servers and EUMETSAT Data Center (EDC).

The OSI SAF wind team releases scatterometer wind software which are distributed by the NWP SAF.

See the Product Navigator for detailed information on the OSI SAF products.

SAF topology and architecture

R&D and operations activities are shared among the consortium.

The production and associated services are based on three 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.
