      The ESA's Soil Moisture and Ocean Salinity (SMOS, 2009-2017) is the first mission using L-band radiometry to monitor the Earth's global surface soil moisture (SM). After more than 7 years in orbit, many studies have ...
    • Assessment of multi-scale SMOS and SMAP soil moisture products across the Iberian Peninsula 

      Portal González, Gerard; Jagdhuber, Thomas; Vall-Llossera Ferran, Mercedes Magdalena; Camps Carmona, Adriano José; Pablos Hernánez, Miriam; Entekhabi, Dara; Piles, María (Multidisciplinary Digital Publishing Institute (MDPI), 2020-02-01)
      Article
      Open Access
      In the last decade, technological advances led to the launch of two satellite missions dedicated to measure the Earth’s surface soil moisture (SSM): the ESA’s Soil Moisture and Ocean Salinity (SMOS) launched in 2009, and ...
    • Comparación entre los productos de humedad del suelo SMOS y ECV 

      Portal González, Gerard (Universitat Politècnica de Catalunya, 2015-09)
      Master thesis (pre-Bologna period)
      Open Access
      The SMOS mission is providing the first ever global observations of surface soil moisture (SSM) at L-band. With almost five years of mapping this variable, it is now possible to start analyzing SSM spatial and temporal ...
    • Influence of quality filtering approaches in BEC SMOS L3 soil moisture products 

      Pablos, Miriam; Vall-Llossera Ferran, Mercedes Magdalena; Piles, María; Camps Carmona, Adriano José; González-Haro, Cristina; Turiel, Antonio; Herbert, Christoph Josef; Chaparro Danon, David; Portal González, Gerard (2019)

      After more than 8 years in orbit the Soil Moisture and Ocean Salinity (SMOS) satellite is still in good health and several algorithms for improving its spatial resolution have been proposed and validated in a variety of ...
    • Sensitivity of TDS-1 GNSS-R reflectivity to soil moisture: global and regional differences and impact of different spatial scales 

      Camps Carmona, Adriano José; Vall-llossera, M.; Hyuk, Park; Portal González, Gerard; Rossato, Luciana (Multidisciplinary Digital Publishing Institute (MDPI), 2018-11-01)
      Article
      Open Access
      The potential of Global Navigation Satellite Systems-Reflectometry (GNSS-R) techniques to estimate land surface parameters such as soil moisture (SM) is experimentally studied using 2014-2017 global data from the UK ...
    • Sensitivity to Soil Moisture and Observation Geometry of Spaceborne GNSS-R Delay-Doppler Maps 

      Hyuk, Park; Camps Carmona, Adriano José; Castellví Esturi, Jordi; Vall-Llossera Ferran, Mercedes Magdalena; Portal González, Gerard; Spatafora, Luciana Rossato (2019)
      Conference lecture
      Open Access
      Thanks to the successful operations of the UK TDS-1 and NASA CYGNSS GNSS-R missions, a wealth of Delay-Doppler Maps (DDM) are being measured from the ocean, but also from land reflections. Using the land reflected DDM, ...
