    • Surface topography and mixed-pixel effects on the simulated L-band brightness temperatures. 

      Talone, Marco; Camps Carmona, Adriano José; Monerris Belda, Alessandra; Vall-Llossera Ferran, Mercedes Magdalena; Ferrazzoli, P.; Piles, Maria (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2007-07-31)
      Article
      Accés obert
      The impact of topography and mixed pixels on L-band radiometric observations over land needs to be quantified to improve the accuracy of soil moisture retrievals. For this purpose, a series of simulations has been performed ...
    • The Emissivity Of Foam-Covered Water Surface At L-Band: Theoretical Modeling And Experimental Results From The FROG 2003 Field Experiment 

      Camps Carmona, Adriano José; Vall-Llossera Ferran, Mercedes Magdalena; Villarino Villarino, Ramón; Reul, Nicolas; Chapron, Bertrand; Corbella Sanahuja, Ignasi; Duffo Ubeda, Núria; Torres Torres, Francisco; Miranda Mendoza, Jorge José; Sabia, Roberto; Monerris Belda, Alessandra; Rodríguez Sánchez, Rubén (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2005-05-31)
      Article
      Accés obert
      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. ...
