Abstract
SMOS (Soil Moisture and Ocean Salinity) is an Earth observation satellite from the European Space Agency launched in November 2009. It is the first satellite mission addressing the challenge of measuring sea surface salinity, never attempted before due to its technical complexity. It uses a microwave interferometric radiometer with aperture synthesis that generates brightness temperature images at 1.4 GHz, from which both geophysical variables are derived using their influence on the dielectric constant of the emitting body, land or ocean. This paper presents the principles of operation of the instrument, the algorithmic approach implemented for the retrieval of...
