Improved relation between radar backscatter from the ocean surface and surface wind vector
conference paper
The simulated VIERS backscatter, obtained using the ECMWF wind and WAM wave fields,
was compared with the backscatter as observed by the ERS1I satellite. The air-sea temperature difference
was set to zero since neutral stability is the most common situation that occurs over the oceans. The period
of interest was the 6th of November 1991 at l2.OO hr.. The simulated backscatter shows an overall good
agreement with the observed ones, even for low wind speed. As a benchmark, we have also compared with
the results of the present operational scatterometer algorithm CMOD4. W conclude from this his comparison
that the VIERS-1 scatterometer algorithm, based on our present knowledge of air-sea interaction, is
performing well, even compared to CMOD4.
