    RFI (Radio Frequency Interference) sources, Sun signal and even land-sea transitions may generate large sidelobes that corrupt SMOS brightness temperature products and therefore, the quality of the soil moisture and sea ...
  • L-Band Sea Surface Emissivity: Preliminary Results Of The WISE-2000 Campaign And Its Application To Salinity Retrieval In the SMOS Mission 

    Camps Carmona, Adriano José; Corbella Sanahuja, Ignasi; Vall-Llossera Ferran, Mercedes Magdalena; Duffo Ubeda, Núria; Torres Torres, Francisco; Villarino Villarino, Ramón; Enrique, L.; Julbé, F.; Font, Jordi; Julià, A.; Gabarró Prats, Carolina; Etcheto, Jacqueline; Boutin, Jacqueline; Weill, Alain; Caselles, Vicente; Rubio, Eva; Wursteisen, Patrick (2003-06-30)

    Soil moisture and ocean salinity at surface level can be measured by passive microwave remote sensing at L-band. To provide global coverage data of soil moisture and ocean salinity with three-day revisit time, the Earth ...
  • Nodal sampling: a new image reconstruction algorithm for SMOS 

    Gonzalez Gambau, Verónica; Turiel, Antonio; Olmedo Casal, Estrella; Martinez, Justino; Corbella Sanahuja, Ignasi; Camps Carmona, Adriano José (Institute of Electrical and Electronics Engineers (IEEE), 2016-04-01)
