    A downscaling approach to improve the spatial resolution of Soil Moisture and Ocean Salinity (SMOS) soil moisture estimates with the use of higher resolution visible/infrared (VIS/IR) satellite data is presented. The ...
  • 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)
    Article
    Restricted access - publisher's policy
    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), ...
  • Improving the accuracy of soil moisture retrievals using the phase difference of the dual-polarization GNSS-R interference patterns 

    Alonso Arroyo, Alberto; Camps Carmona, Adriano José; Aguasca Solé, Alberto; Forte, G.; Monerris Belda, Sandra; Ruediger, Christoph; Walker, Jeffrey; Hyuk, Park; Pascual, D.; Onrubia Ibáñez, Raúl (2014-12-01)
    Article
    Open Access
    Soil moisture (SM) is a key parameter in the climate studies at a global scale and a very important parameter in applications such as precision agriculture at a local scale. The Global Navigation Satellite Systems Interference ...
  • The dual polarization GNSS-R interference pattern technique 

    Alonso Arroyo, Alberto; Camps Carmona, Adriano José; Monerris Belda, Sandra; Ruudiger, C.; Walker, Jeffrey; Forte Veliz, Giuseppe Francesco; Pascual Biosca, Daniel; Hyuk, Park; Onrubia Ibáñez, Raúl (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report
