The first version of satellite Sea Surface Salinity (SSS) maps produced by the ESA CCI (Climate Change Initiative) SSS project by combining SMOS-CATDS, AQUARIUS and SMAP SSS over the 2010-2018 period are now available. Systematic differences between SSS obtained from the various instruments and under various geometries have been homogenized  using a methodology similar to the one developed and implemented at CATDS (Centre Aval de Traitement des Données SMOS).

SSS maps as derived from SMOS+ AQUARIUS (2012) and from SMOS+SMAP (2017) : see in particular the interannual variation of the SSS in the Amazon plume, off the Rio De La Plata and the Mississippi river plumes.
