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
Restricted access - publisher's policyRadio 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 ... -
Impact of amplitude calibration errors on SMOS global images
Durán Martínez, Israel; Corbella Sanahuja, Ignasi; Torres Torres, Francisco; Duffo Ubeda, Núria; Oliva, Roger; Martín Neira, Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2016)
Conference report
Restricted access - publisher's policySome of the artifacts observed in SMOS brightness temperature images are originated in an inconsistency between correlation and antenna temperature calibration errors, which produces a multiplicative bias that scales with ... -
Impact of antenna tuning on SMOS correlation loss
Torres Torres, Francisco; Durán Martínez, Israel; Corbella Sanahuja, Ignasi; Duffo Ubeda, Núria; Closa, Josep; Oliva, Roger; Martín-Neira, Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2016)
Conference report
Restricted access - publisher's policyThe Soil Moisture and Ocean Salinity (SMOS) mission by the European Space Agency (ESA) was launched in 2009 [1]. Since then, it has produced a continuous stream of valuable geophysical data over land, ice and ocean [2] ... -
SMOS instrument performance and calibration after 6 years in orbit
Martín Neira, Manuel; Oliva, Roger; Corbella Sanahuja, Ignasi; Torres Torres, Francisco; Duffo Ubeda, Núria; Durán Martínez, Israel; Kainulainen, Juha; Closa, Josep; Zurita Campos, Alberto Manuel; Cabot, François; Khazaal, Ali; Anterrieu, E.; Barbosa, José; Tenerelli, Joseph (Institute of Electrical and Electronics Engineers (IEEE), 2016)
Conference report
Open AccessESA’s Soil Moisture and Ocean Salinity (SMOS) mission has been in orbit for over 6 years, and its Microwave Imaging Radiometer with Aperture Synthesis (MIRAS) in two dimensions keeps working well. The data for almost this ... -
