Abstract The artificial gravel augmentation of river channels is increasingly being used to mitigate the adverse effects regulation and sediment starvation. A systematic framework for designing assessing such augmentations still lacking, notably on large rivers. Monitoring required quantify movement augmented gravel, measure bedform changes, assess potential habitat enhancement, reduce uncertainty in management. Here we present results an experiment conducted Rhine River (French German...
Abstract. In biogeochemical models coupled to ocean circulation models, vertical mixing is an important physical process which governs the nutrient supply and plankton residence in euphotic layer. However, often poorly represented numerical simulations because of approximate parameterizations sub-grid scale turbulence, wind forcing errors other mis-represented processes such as restratification by mesoscale eddies. Getting a sufficient knowledge nature structure these necessary implement...
Abstract. The objective of this paper is to investigate if the description ocean uncertainties can be significantly improved by applying a local anamorphic transformation each model variable, and making assumption joint Gaussianity for transformed variables, rather than original variables. For that purpose, it first argued significant improvement already obtained deriving transformations from simple histogram marginal distributions. Two distinctive advantages solution large size applications...

The signal recorded by the sensor at satellite level contains information relative both to atmosphere and surface. Atmospheric correction is therefore necessary extract surface reflectance required within biophysical algorithms used estimate canopy attributes. Aerosol characteristics are difficult evaluate because they vary rapidly with time space. objective of this study develop an autonomous aerosol method exploiting content in MERIS images. A dedicated neural network was trained retrieve...
This study aims at developing an autonomous atmospheric correction method, that is exploiting the information content in image of satellite considered. The signal recorded by sensor contains relative both to atmosphere and surface. Aerosol characteristics are most difficult evaluate because they vary rapidly with time space. spectral variation radiance signal, when enough sampled sensor, generally allows decoupling aerosol effects from However, on non vegetated areas or region low vegetation...
The CYTTARES database (CYclopes Training and Testing Algorithm Reference Ensemble of Sites) is composed many sites representing the whole biome over globe. This selection based on ECOCLIMAP dataset uses various specific criteria, such as existing networks site homogeneity, topography, geographical location. 532 are selected globe, including 137 from AERONET to future atmospheric correction VALERI for a comparison with available ground observations. Then, 98 additional come international...
