English abstract:
Soil moisture is an important parameter for hydrological modeling and crop yield
prediction. The ability of radar sensors to monitor SM has been demonstrated in numerous
studies. Yet, only coarse resolution (>25km) SM products are available over the European
continent. In this work, the soil moisture product derived from the ERS scatterometer data at
50 km spatial resolution is presented and a downscaling technique is evaluated that provides
SM at 1 km scale. The presented downscaling technique stands upon the concept of temporal
stability of SM. Despite the high heterogeneity of the study area, additional SM information to
that demonstrated by the ERS data could be retrieved from the downscaled product at 1 km
spatial resolution. The SM patterns of the downscaled product correlated to the 1 km SM data
from the ENVISAT Advanced Synthetic Aperture Radar (ASAR) Global Mode (GM). While
these findings are preliminary, they provide promising results for the hydrological and
meteorological community operating at spatial scales of 5 km and higher.
