Ocean Surface Current Analysis-Real-time (OSCAR) (Bonjean and Lagerloef 2002,
J. Phys. Oceanogr., Vol. 32, No. 10, 2938-2954; Lagerloef et al. 1999, JGR-Oceans, 104, 23313-23326).
(top) Total velocity. Satellite data included Jason sea level anomalies and QuickScat winds.
Data were smoothed with optimal filter (Lx~10, Ly~2). (bottom) Velocity anomalies. The subtracted
climatology was based on SSM/I and QuickScat winds and Topex/Poseidon and Jason from 1993-2010.
