Abstract :
In order to make a qualitative assessment on the error of retrieved sea surface salinity (SSS), the simulating tool developed by P. Waldteufel tuned to SMOS characteristics is used in combination with numerical models outputs, remotely sensed data and in-situ data. A space-time average is carried out in order to reduce the SSS error. Its impact is presented for some specific regions.
