English abstract:
A surface soil moisture (SSM) product at 1 km spatial resolution derived from the ENVISAT ASAR GM data series was evaluated over Africa using coarse spatial resolution SSM acquisitions from the AMSR-E radiometer and GLDAS-NOAH model. A good ability (R=~0.6) of ASAR GM product to detect spatio-temporal variability of SSM was found over region with low to medium dense vegetation and yearly rainfall >250 mm. These findings agree with previous evaluation studies over Australia and further strengthen understanding of the quality of the product and its possible use in data assimilation. Problems were detected in the ASAR GM algorithm over arid regions. Their solutions are being considered and are expected to bring further improvement to the algorithm.
