English abstract:
ASCAT and SMOS soil moisture products were validated
for the year 2010 in the Rur and Erft catchments in the west
of Germany. In situ data of three test sites of the TERENO
initiative were used to calibrate the hydrological model
WaSiM-ETH, which was applied to generate a soil moisture
reference for the whole study area. Comparison of SMOS
soil moisture with the reference displayed a high dry bias
and low to moderate correlations. ASCAT soil moisture
showed higher correlations and no bias. A temporal stability
analysis exhibits low stability of the SMOS data and higher
stability of ASCAT data. Generally, the performance of
ASCAT is well, while there are still some problems with soil
moisture retrieval and RFI in the SMOS soil moisture
