Observing oceans from space

How do you use OSI SAF products ? Please fill our online survey to help us improve our products and plan our 4th five-year period (2022-2027).

The OSI SAF develops, processes and distributes, in near real-time, products related to key parameters of the ocean-atmosphere interface. Products are accessible on local FTP servers with flexible extraction interface, EUMETCast, and EUMETSAT Data Center (EDC). The OSI SAF also offers climatological data records. The OSI SAF team focuses on scatterometer winds (and soon microwave winds), Sea Surface Temperature (SST) and sea Ice Surface Temperature (IST), radiative fluxes : Downward Longwave Irradiance (DLI) and Surface Solar Irradiance (SSI), sea ice concentration, edge, type, emissivity, drift.
The OSI SAF currently use data from meteorological satellites both in geostationary and polar orbit.

Top story


In the frame of the NWP SAF and of the OSI SAF, the scatterometer team at KNMI assessed the performance of CFOSAT and WindRad Rotating Fan-beam Scatterometer Simulation and Wind Retrieval.

Here below, Zhen Li explains briefly what was done and what was found during this study.

What did we do?

  • Built a simulation framework for all existing rotating-beam scatterometer types (rotating fan-beam and rotating pencil-beam).
