- The left panel corresponds to the ``before" picture, where the error is between the background and true fields and the right one corresponds to the ``after" picture, where the error is between the corrected and true fields. On top of that, we observe the excellent agreement between the positions of the drifters simulated with the corrected field and the true observations. Next, the correction in terms of the velocity direction is shown in Fig.~\ref{fig:cerror}: we display the cosine of the angle between the background and true field on the left side versus the  cosine of the angle between the corrected and true fields on the right. Note that a cosine of one indicates a strong correlation (dark red) in direction between the two fields. We see this strong correlation between true and corrected fields by observing how the blue color (left pannel of Fig.~\ref{fig:cerror}) turns into deep red (right pannel of Fig.~\ref{fig:cerror}) in the region where the drifters were deployed. Finally, in Fig. \ref{fig:summary}, we show the actual current maps before and after correction. We clearly see that the drifters corrected the poorly represented coastal meander in the AVISO altimetric velocity field.
