The validation of SMOS L2 soil moisture data requires the maintenance of long-term soil moisture monitoring sites. One such site is the Upper Danube SMOS validation site situated in Southern Germany with a size of 77000 km2. Since 2007, the University of Munich routinely collects in situ soil moisture data within the test site in preparation for the SMOS validation. An operational framework has been...
Modeling of snow emission at microwave frequencies is necessary in order to understand the complex relations between the emitted brightness temperature and snowpack characteristics such as density, grain size, moisture content, and vertical structure. Several empirical, semiempirical, and purely theoretical models for the prediction of snow emission properties have been developed in recent years....
In this paper a modified three component polarimetric decomposition incorporating multi-angular acquisitions is developed to estimate soil moisture under vegetation cover over agricultural areas. The approach is applied on fully-polarimetric L-band data acquired by DLR's airborne E-SAR sensor in the frame of the OPAQUE campaign conducted in May 2008 in the Wei??eritz catchment area, near Dresden,...
