Sea surface salinity can be measured by microwave radiometry at L-band (1400–1427 MHz). This frequency is a compromise between sensitivity to the salinity, small atmospheric perturbation, and reasonable pixel resolution. The description of the ocean emission depends on two main factors: 1) the sea water permittivity, which is a function of salinity,(More)
Soil Moisture and Ocean Salinity (SMOS) is an Earth Explorer Opportunity Mission from the European Space Agency with a launch date in 2007. Its goal is to produce global maps of soil moisture and ocean salinity variables for climatic studies using a new dual-polarization L-band (1400–1427 MHz) radiometer Microwave Imaging Radiometer by Aperture Synthesis(More)
In May 1999, the European Space Agency (ESA) selected the Earth Explorer Opportunity Soil Moisture and Ocean Salinity (SMOS) mission to obtain global and frequent soil moisture and ocean salinity maps. SMOS single payload is the Microwave Imaging Radiometer by Aperture Synthesis (MIRAS), an L-band two-dimensional aperture synthesis radiometer with(More)
 Drastically different sea states result for a growing, decaying, or a fully-developed sea due to the presence of a wind field [1]. In addition, the sea state is altered by the superposition of oceanic currents on the wave field created by the wind. This study presents a numerical analysis of the change in the sea surface brightness temperature at L-band(More)
This work summarizes the main findings of the activities carried out in the past years by the Microwave Radiometry Team at the Technical University of Catalonia (UPC) in the field of sea surface salinity retrieval within the frame of the SMOS mission in collaboration with the Institute of Marine Sciences (ICM/CMIMA-CSIC). They cover the measurement of the(More)
The SMOS (Soil Moisture and Ocean Salinity) mission will provide from 2007 onwards global maps of soil moisture over land and sea surface salinity over ocean. The radiometry group of the Technical University of Catalonia (UPC) in Barcelona has been involved either in the definition of the SMOS single payload, MIRAS (Microwave Imaging Radiometer by Aperture(More)
