ResumenSince its launch in November 2009, the Soil Moisture Ocean Salinity (SMOS) satellite has been sending measures of the brightness temperature emitted by the earth surface at the microwave L-band. This information is being used to retrieve values of the sea surface salinity (SSS) and soil moisture. A hierarchy of SSS products has been defined in the SMOS data processing chain. This work focuses on the so called Level 3 (binned maps of SSS) and Level 4 (products combining SMOS data with any other source of information). In this work it is proved that a simple, but robust, data assimilation technique may be used to produce Level 4 maps of SSS by assimilating Level 3 SSS data. The numerical ocean model used here is a regional simulation of the North-Atlantic ocean. The resulting SSS is closer to in-situ (independent) SSS estimates, and the geophysical distribution of the singularity exponents has similar features that to the ones present in the singularity maps of sea surface temperature
