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

On the left hand side of the figure, you can see the SST climatology derived from the OSTIA reanalysis.
The right hand side shows the SST from the OSI SAF processing of Metop AVHRR: we can see a warming of more than 5°C between the 21st and the 25th of June 2020.
This warming is much greater than usual as you can see on the SST climatology. This rapid warm-up is in correlation with the heat peak linked to a powerful high pressure which was positioned around Belgium on June 23.
