    Capability for sea surface salinity observation was an important gap in ocean remote sensing in the last few decades of the 20th century. New technological developments during the 1990s at the European Space Agency led to ...
  • Dual-polarization GNSS-R interference pattern technique for soil moisture mapping 

    Alonso Arroyo, Alberto; Camps Carmona, Adriano José; Aguasca Solé, Alberto; Forte Veliz, Giuseppe Francesco; Monerris Belda, Alessandra; Rudiger, Christoph; Walker, Jeffrey; Hyuk, Park; Pascual Biosca, Daniel; Onrubia Ibáñez, Raúl (2014-05-01)

    The interference pattern technique (IPT) consists of the coherent addition of the direct and reflected global navigation satellite systems (GNSS) signals in the receiving antenna. The detected power oscillates (fading), ...
  • Experimental estimation of soil emissivity and its application to soil moisture retrieval in the SMOS Mission 

    Monerris Belda, Alessandra (Universitat Politècnica de Catalunya, 2009-09-07)
    Doctoral thesis
  • Numerical simulation of the full-polarimetric emissivity of vines and comparison with experimental 

    Martínez Vazquez, Alberto; Camps Carmona, Adriano José; López-Sánchez, Juan Manuel; Vall-Llossera Ferran, Mercedes Magdalena; Monerris Belda, Alessandra (2009-07)
    Article
    Open Access
    Surface soil moisture is a key variable needed to understand and predict the climate. L-band microwave radiometry seems to be the best technique to remotely measure the soil moisture content, since the influence of other ...
  • SMOS REFLEX 2003: L-Band Emissivity Characterization of Vineyards 

    Vall-Llossera Ferran, Mercedes Magdalena; Camps Carmona, Adriano José; Corbella Sanahuja, Ignasi; Torres Torres, Francisco; Duffo Ubeda, Núria; Monerris Belda, Alessandra; Sabia, Roberto; Selva Valero, Daniel; Antolín, Carmen; López Baeza, Ernesto; Ferrer, Joan Ferran; Saleh, Kauzar (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2005-05-31)
    Article
    Open Access
    The goal of the Soil Moisture and Ocean Salinity mission over land is to infer surface soil moisture from multiangular L-band radiometric measurements. As the canopy affects the microwave emission of land, it is necessary ...

  • 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
    Open Access
    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 

    Rodríguez, R; Monerris Belda, Alessandra; Sabia, Roberto; Miranda Mendoza, Jorge José; Camps Carmona, Adriano José; Vall-Llossera Ferran, Mercedes Magdalena; Villarino Villarino, Ramón; Reul, N; Chapron, B; Corbella Sanahuja, Ignasi; Duffo Ubeda, Núria; Torres Torres, Francisco (IEEE Press. Institute of Electrical and Electronics Engineers, 2005-05)
    Article
    Open Access
    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. ...
