We are grateful for funding from the National Science Foundation (Grants OCE-0220563 and ATM-0623402). The altimeter products were produced by SSALTO/DUACS and distributed by AVISO, with support from CNES. The buoy data were obtained from the PIRATA Project and the gridded QuikSCAT data were produced by COAPS/FSU through support by the NASA Ocean Vector Winds Science Team. We warmly thank Mark A. Bourassa for his help in understanding different wind products.
