Approche globale de caractérisation du comportement électromagnétique des sols en bande L - Application au suivi par télédétection spatiale de l'humidité des sols.

Abstract : Energy and matter fluxes between the atmosphere and the land surface are affected by hydrological states of the terrestrial land surface . We must increase our knowledge of these transfer processes to improve research on climate change. To reach these objectives, we must obtained global information on the hydrological states and properties of the land-surface. The microwave remote sensing instruments are an adequate way to provide soil moisture information at large scale. Microwave remote sensing data are linked to the soil moisture but also to the roughness, texture and the physicochemical properties of the soil. In that context, the objective of this study is to develop an integrated approach to estimate effective electromagnetic properties of soils layers using ground-penetrating radar (GPR), L-band radiometer, dielectric laboratory measurements, modelling approaches and in situ measurements of essential state variables.
