Abstract :
The European Space Agency has launched, November 2nd, 2009, the SMOS mission devoted to the monitoring of Soil Moisture and Ocean Salinity at global scale from L-band space borne radiometric observations obtained with a two dimensional interferometer. This paper is concerned with the retrieval of radiometric brightness temperature maps from interferometric level 1A data provided by SMOS. The impact of some missing data, due to two kinds of failures correlator/receiver failure on the stability of the retrieval method is studied in depth.
