Abstract

The present case study focuses on monitoring the wetness state of the experimental Bibeschbach catchment (10.8 km²), located within the Alzette river basin in the Grand-Duchy of Luxemburg over the last three winters (2005-2008). The objectives of this study are (1) to retrieve soil moisture from spaceborne active and passive microwave sensors, namely AMSR-E and ERS-2 SAR, (2) to compare the remote sensing-derived estimates of basin-averaged soil moisture with ground measurements that are performed throughout the catchment.
