Abstract :
A collocated TOPEX/NSCAT/ECMWF dataset is compiled to investigate the systematic discrepancies among the three kinds of wind estimates. It is found that the discrepancy between TOPEX and NSCAT winds is characterized by a significant "phase opposition" with respect to latitude, season and wind intensity.
