Since the beginning of the ERS-1 Scatterometer mission in 1991 a long dataset
of backscattering signal from the Earth surface is available for studies and
The Scatterometer has been originally designed for wind retrieval over the
ocean but now it is proved that Scatterometer data may be also useful for
other applications over land such as soil moisture, vegetation and ice cover
which require high spatial resolution products.
The need of high quality products and of a long homogeneous set of
measurements has leaded ESA to develop the project Advanced Scatterometer
Processing System (ASPS). The aim of the ASPS is to reprocess the entire
ERS1/2 Scatterometer mission data set as well as to provide new scientific
products with an enhanced resolution (25km).
The scope of this paper is to present to the users community the description
of the new ASPS product, an overview of the ASPS system, the current state of
the ERS-2 Scatterometer instrument and the quality of the measurements .
