Observing oceans from space

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 context of the OSI SAF Visiting Scientist Program, Marko Mäkynen from the Finnish Meteorological Institute worked on the reduction of sea-ice concentration noise using brightness temperature correction. This work took place from November 2019 to May 2020 and was supervised by Rasmus Tonboe from DMI.
