Paper Abstract

This paper analyses eight different remote sensing campaigns carried out from 1998 to 2001, pointing out the backscattering coefficients behaviour in dependence both to soil moisture and roughness. Our study indicates a clear dependence of backscattering coefficients on soil moisture with an average sensitivity of 0.25 dB/gr/cm3. In a subsequent step these data sets are utilised to validate an inversion procedure based on a Bayesian algorithm aimed at extracting soil moisture information from backscattering coefficients. After a first run, a priori soil moisture information deriving from the simulation of a hydrological model is introduced leading to an improvement both in extracted soil moisture values and in their uncertainties.
