    • 2000 days of SMOS at the Barcelona Expert Centre: a tribute to the work of Jordi Font 

      Turiel Martínez, Antonio; Piles Guillem, Maria; González Gambau, V.; Ballabrera Poy, Joaquim; Gabarró Prats, Carolina; Martinez, Justino; Olmedo, Estrella; Portabella, Marcos; Pérez López, Fernando; Solé Ollé, Jordi (2016-09-01)
      Article
      Open Access
      Soil Moisture and Ocean Salinity (SMOS) is the first satellite mission capable of measuring sea surface salinity and soil moisture from space. Its novel instrument (the L-band radiometer MIRAS) has required the development ...
    • A downscaling approach for SMOS land observations: evaluation of high-resolution soil moisture maps over the Iberian Peninsula 

      Piles Guillem, Maria; Sanchez, Nilda; Vall-Llossera Ferran, Mercedes Magdalena; Camps Carmona, Adriano José; Martinez Fernandez, Jose; Martinez, Justino; González Gambau, Veronica (2014-09-01)

      The ESA's Soil Moisture and Ocean Salinity (SMOS) mission is the first satellite devoted to measure the Earth's surface soil moisture. It has a spatial resolution of similar to 40 km and a 3-day revisit. In this paper, a ...
    • A novel reconstruction algorithm for the improvement of SMOS brightness temperatures 

      González Gambau, Veronica; Turiel, Antonio; Martinez, Justino; Olmedo, Edson; Corbella Sanahuja, Ignasi (Institute of Electrical and Electronics Engineers (IEEE), 2014)
      Conference report
      Restricted access - publisher's policy
      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 ...
    • From field experiments to salinity products: a tribute to the contributions of Jordi Font to the SMOS mission 

      Camps Carmona, Adriano José; Gabarró Prats, Carolina; Vall-Llossera Ferran, Mercedes Magdalena; Blanch Boris, Sebastián; Aguasca Solé, Alberto; Torres Torres, Francisco; Corbella Sanahuja, Ignasi; Duffo Ubeda, Núria; Turiel Martínez, Antonio; Portabella, Marcos; Ballabrera Poy, Joaquim; González Gambau, V.; Martinez, Justino; Villarino Villarino, Ramón; Monerris Belda, Sandra; Bosch Lluís, Xavier; Sabia, Roberto; Talone, Marco; Piles Guillem, Maria; Pablos Hernánez, Miriam; Valencia Domènech, Enric (2016-09-01)
      Article
      Open Access
      This article summarizes some of the activities in which Jordi Font, research professor and head of the Department of Physical and Technological Oceanography, Institut de Ciències del Mar (CSIC, Spanish National Research ...
    • 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)
      Article
      Open Access
      Soil moisture and ocean salinity (SMOS) brightness temperature (TB) images and calibrated visibilities are related by the so-called G -matrix. Due to the incomplete sampling at some spatial frequencies, sharp transitions ...
    • On the synergy of SMOS and Terra/Aqua MODIS: high resolution soil moisture maps in near real-time 

      Piles Guillem, Maria; Vall-Llossera Ferran, Mercedes Magdalena; Camps Carmona, Adriano José; Sanchez, Nilda; Martinez Fernandez, Jose; Martinez, Justino; Gonzalez Gambau, Verónica; Riera, R. (Institute of Electrical and Electronics Engineers (IEEE), 2013)
      Conference report

      An innovative downscaling approach to obtain fine-scale soil moisture estimates from 40 km SMOS observations has been developed. It optimally blends SMOS multi-angular and full-polarimetric information with MODIS visible/data ...
    • SMOS and aquarius radiometers: inter-comparison over selected targets 

      Pablos Hernández, Miriam; Piles Guillem, Maria; González Gambau, Veronica; Vall-Llossera Ferran, Mercedes Magdalena; Camps Carmona, Adriano José; Martinez, Justino (2014-09-01)
      Article
      Restricted access - publisher's policy
      Passive microwave remote sensing at L-band is considered to be the most suitable technique to measure soil moisture and ocean salinity. These two variables are needed as inputs of predictive models, to improve climate and ...
