The laboratory has developed an expertise in the use of scatterometers sensor over sea ice, and has built a unique continuous backscatter data archive since 1991 from C and Ku-band sensors. Backscatter data can be used for sea ice type detection. It has been also shown that the combination of these data with passive satellite-borne sensors measurements is very useful for sea ice displacement estimation. A unique 1992-present Arctic sea ice drift dataset (lien vers la news Drift) has been created. These parameters and also sea ice concentration for both poles are inferred daily, archived and distributed by the CERSAT, freely available for the scientific and operational communities.
The sea ice team is involved in projects funded by E.U. and European and french space agencies (CONVECTION, DAMOCLES, GlobIce, CCI, Monarch-A, etc...).
