Assessing the accuracy of satellite derived ocean currents by comparing observed and virtual buoys in the Greater Agulhas Region

Author: Hart-Davis, MG ; Backeberg, Bjorn-Christoph ; Halo, I ; Van Sebille, E ; Johannessen, JA Date: Oct 2018 In this study, we assess the accuracy of a combined geostrophic and Ekman current product (GlobCurrent) that estimates ocean currents at 15m depth, by coupling it to a synthetic particle tracking tool and comparing the virtual trajectories ...

Mapping the Agulhas Current from space: an assessment of ASAR surface current velocities

Author: Rouault, Marjolaine J ; Mouche, A ; Collard, F ; Johannessen, JA ; Chapron, B Date: Oct 2010 Over 2 years of surface current information collected in the Agulhas Current region and derived from the Doppler centroid anomalies of Envisat’s advanced synthetic aperture radar (ASAR) are examined. The sources of errors and potential use ... Read more
Measuring surface current velocities in the Agulhas region with ASAR

Author: Rouault, Marjolaine J ; Mouche, A ; Collard, F ; Johannessen, JA ; Chapron, B Date: Jan 2010 Surface current information collected over the Agulhas Current region and derived from the Doppler centroid anomalies of the Advanced Synthetic Aperture Radar (ASAR) are examined. The sources of errors and potential use of the radar surface ... Read more
