Short summary
The Surface Water and Ocean Topography satellite gives high-resolution sea surface height data, yet converting these data into accurate ocean current maps is difficult.

The results show a scale-dependent trade-off: one product is best for large-scale currents, another captures finer details, and a third performs steadily overall. These insights help users in selecting the right product for their work.
