Yann Kerr,Ali Mahmoodi,Arnaud Mialon,Ali Al Biltar,Nemesio Rodriguez-Fernandez,Philippe Richaume,Francois Cabot,Jean-Pierre Wigneron,Philippe Waldteufel,Paolo Ferrazzoli,Mike Schwank,Steven Delwart +11 more
TL;DR: In this article, a neural network approach was developed to estimate soil moisture fields in near-real time from the L-band 2D interferometric radiometer in the 1400-1427 MHz protected band.
Proceedings ArticleDOI
Lessons learnt from SMOS after 7 years in orbit
Manuel Martin-Neira,Roger Oliva,Ignasi Corbella,Francesc Torres,Nuria Duffo,Israel Duran,Juha Kainulainen,Josep Closa,Alberto Zurita,Francois Cabot,Ali Khazaal,Eric Anterrieu,Jose Barbosa,Goncalo Lopes,Joe Tenerelli,Raul Diez-Garcia,Jorge Fauste,Veronica Gonzalez-Gambau,Antonio Turiel,Steven Delwart,Raffaele Crapolicchio,Martin Suess,Susanne Mecklenburg,Matthias Drusch,Roberto Sabia,Elena Daganzo-Eusebio,Yann Kerr,Nicolas Reul +27 more
TL;DR: The lessons learnt from SMOS are presented, including the things that work well, those that need improvement, and how the instrument could be enhanced if the authors were to build it again.
Overview on calibration and validation activities for ESA's Soil Moisture and Ocean Salinity Mission
TL;DR: The paper will give an overview on the scientific objectives and the (access to the) available data products.
Proceedings ArticleDOI
Enhancement of diffusers BSDF accuracy: spectral features effect
Hedser van Brug,Gregory Bazalgette Courreges-Lacoste,Gerard Otter,Jos Groote Schaarsberg,Steven Delwart,Umberto del Bello +5 more
TL;DR: In this article, the authors investigated the effect of diffusers in the vacuum of space on the BSDF (Bi-directional Scattering Distribution Function) with respect to the one in ambient conditions.
Proceedings ArticleDOI
Overview on calibration and validation activities for ESA's soil moisture and ocean salinity mission
TL;DR: The Soil Moisture and Ocean Salinity (SMOS) mission is the European Space Agency's (ESA) second Earth Explorer Opportunity mission as mentioned in this paper, which directly responds to the current lack of global observations of soil moisture and ocean salinity, two key variables used in predictive hydrological, oceanographic and atmospheric models.
