Abstract :
With the advent of ESA´s SMOS Mission, we have the opportunity for the first time of measuring Sea Surface Salinity (SSS) from the space and at a synoptic scale. However, the MIRAS instrument onboard SMOS is a new concept of instrument, and the adjustment and calibration of this interferometric radiometer poses great challenges. In this paper, we show the present status of Level 3 and 4 salinity maps, which are supposed to give accurate climatological descriptions of SSS, describing the attained accuracy and analyzing the geophysical consistence of those maps. A discussion on future improvements is also issued.
