| Abstract: | This is the first multiplatform evaluation involving data from the new Sentinel-3A altimeter. An
experiment was undertaken in the Algerian Basin, employing an ocean glider and a ship mission, along the
same track and synchronous with an overpass of the Sentinel-3A mission. This provided three independent
views of the ocean velocity field, along a section that encompassed three different oceanographic regimes.
The results demonstrate the capacity of Sentinel-3A to retrieve fine-scale oceanographic features (~20 km).
The intercomparison with in situ platforms showed a significant improvement, order 30% in resolution and
42% in velocity accuracy using a synthetic aperture radar mode with respect to lower-resolution mode of
conventional altimetry. In addition, the three-platform view provided valuable insight into the variability of
evolving oceanographic features, in an area of the Mediterranean that remains chronically under sampled. |
