Journal ArticleDOI
A Modified Soil Adjusted Vegetation Index
TL;DR: In this article, a modified SAVI (MSAVI) was proposed to increase the dynamic range of the vegetation signal while further minimizing the soil background influences, resulting in greater vegetation sensitivity as defined by a vegetation signal to soil noise ratio.
Journal ArticleDOI
The SMOS Mission: New Tool for Monitoring Key Elements ofthe Global Water Cycle
Yann Kerr,Philippe Waldteufel,Jean-Pierre Wigneron,Steven Delwart,Francois Cabot,Jacqueline Boutin,Maria-José Escorihuela,Jordi Font,Nicolas Reul,C. Gruhier,S. Juglea,Mark R. Drinkwater,Achim Hahne,Manuel Martin-Neira,Susanne Mecklenburg +14 more
TL;DR: The SMOS satellite was launched successfully on November 2, 2009, and will achieve an unprecedented maximum spatial resolution of 50 km at L-band over land (43 km on average over the field of view), providing multiangular dual polarized (or fully polarized) brightness temperatures over the globe.
Journal ArticleDOI
Soil moisture retrieval from space: the Soil Moisture and Ocean Salinity (SMOS) mission
TL;DR: The goal of this paper is to present the main aspects of the baseline mission and describe how soil moisture will be retrieved from SMOS data.
Journal ArticleDOI
The SMOS Soil Moisture Retrieval Algorithm
Yann Kerr,Philippe Waldteufel,P. Richaume,Jean-Pierre Wigneron,Paolo Ferrazzoli,A. Mahmoodi,Ahmad Al Bitar,Francois Cabot,C. Gruhier,S. Juglea,Delphine Leroux,Arnaud Mialon,Steven Delwart +12 more
TL;DR: A retrieval algorithm to deliver global soil moisture (SM) maps with a desired accuracy of 0.04 m3/m3 is given, discusses the caveats, and provides a glimpse of the Cal Val exercises.
Journal ArticleDOI
L-band Microwave Emission of the Biosphere (L-MEB) Model: Description and calibration against experimental data sets over crop fields
Jean-Pierre Wigneron,Yann Kerr,Philippe Waldteufel,K. Saleh,M. J. Escorihuela,P. Richaume,Paolo Ferrazzoli,P. de Rosnay,Robert J. Gurney,Jean-Christophe Calvet,Jennifer Grant,M. Guglielmetti,Brian K. Hornbuckle,C. Matzler,Thierry Pellarin,Mike Schwank +15 more
TL;DR: In this article, a detailed description of soil and vegetation modelling in L-MEB is given in order to address these needs, and the use of LMEB in soil moisture retrievals is evaluated for several experimental data sets over agricultural crops.
