    • 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 ...

    • Benefits of applying nodal sampling to SMOS data over semi-enclosed seas and strongly RFI-contaminated regions 

      González Gambau, Verónica; Olmedo, Estrella; Martinez, J.; Turiel, Antonio; Corbella Sanahuja, Ignasi; Oliva, Roger; Martín Neira, Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2018)
      Conference report

      Radio Frequency Interferences (RFI) are still an important source of contamination in SMOS data. The application of nodal sampling (NS) to brightness temperature images helps to mitigate the degradation that RFIs produce ...

    • Dynamic effect of quasi-geostrophic turbulence on ocean surface as derived from satellite imagery 

      Turiel, Antonio (SARTI (Technological Development Centre of Remote Acquisition and Data processing Systems), 2010-03-10)

      Global Soil Moisture and Ocean Salinity (SMOS) Level 3 (L3) soil moisture (SM) products are being routinely distributed by the Barcelona Expert Centre (BEC). The quality and accuracy of these SM products have been demonstrated ...

    • Latitudinal and seasonal SMOS amplitude calibration assessment 

      Gonzalez Gambau, Verónica; Corbella Sanahuja, Ignasi; Torres Torres, Francisco; Duffo Ubeda, Núria; Turiel, Antonio (Institute of Electrical and Electronics Engineers (IEEE), 2014)
      Conference report
      Restricted access - publisher's policy
      The consistency of MIRAS amplitude calibration along the mission is a key issue to ensure a stable and accurate long-term dataset of ESA's SMOS soil moisture and ocean salinity data. Recent studies have revealed latitudinal ...

    • 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 ...

    • Preparing levels 3 and 4 for the SMOS mission 

      Gourrion, Jerôme; Mourre, Baptiste; Ballabrera, Joaquim; Aretxabaleta, Alfredo; Turiel, Antonio (SARTI (Technological Development Centre of Remote Acquisition and Data processing Systems), 2010-03-10)
