English abstract:
Soil moisture is an important environmental variable and a key element in the Earths energy, water and carbon cycle. Monitoring soil moisture over large areas is only feasible using remote sensing. In this paper, a change detection approach based on an extensive Envisat ASAR Global Mode data archive is presented. Actual backscatter measurements are compared to two reference values representing dry and wet soil conditions. Maps showing the surface soil moisture are generated. First validation showed a good agreement with precipitation data and soil moisture measurements. However, the lack of large scale soil moisture monitoring sites makes validation difficult.
