FIGURE A1.4  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. See also http://www.oscar.noaa.gov.
