In the context of soil monitoring from microwave radiometric observations, the knowledge of the soil permittivity is an important factor in order to guarantee the accuracy of models inversions. Previous studies have showed the impact of temperature and moisture gradients in the top soil layer on remote sensing monitoring of soil. So, we aim here to investigate a way to increase our knowledge of the permittivity profile of the top soil layer, in particular at the P and L band. The solution we selected is based on a new equipment for continuous in-situ measurements of dielectric soil profiles. First measurement results over a sandy soil after rainfall are presented.< Réduire
