Abstract :
Surface soil moisture estimation from SAR (ERS-2 and Radarsat) images was investigated using the "water-cloud" model. It was verified that the "water-cloud" model can adequately represent the backscattering coefficients over winter wheat fields, during the entire growing season, as a function of canopy water content and surface soil moisture.
