Abstract :
Soil moisture is a key variable in a number of geophysical and ecological processes. Despite its importance, availability of information on soil moisture is limited. Only recently it could be demonstrated that low resolution radar data in combination with a change detection method can resolve this constraint. Experience gained in a number of successful pilot projects, lead to an initiative, setting up a global soil moisture archive.
