A summary of the VIERS-1 scatterometer model
article
The VIERS-1 (Verification and Interpretation ERS-1) project has resulted in a new algorithm for the interpretation of the wind scatterometer, based on a physical model of air/sea/radar interaction in which the radar backscatter is calculated from wind and wave conditions. The model is inverted to obtain the wind from the radar backscatter. For operational purposes the model was coupled to the WAM wave model, which provides first-guess wave information. The performance of VIERS-1 has been compared with that of CMOD4, the algorithm presently in operational use, which is mainly based on statistical fitting. Using operational data it has been found that the results of VIERS-1 were comparable with those of CMOD4, with VIERS-1 outperforming CMOD4 slightly at both high and low wind speeds, but with CMOD4 providing a somewhat closer fit in backscatter space.
