The new Surface Water and Ocean Topography (SWOT) satellite mission aims to
provide sea surface height (SSH) measurements in two dimensions along a wideswath
altimeter track with an expected effective resolution down to 15–30 km. In
this context our goal is to optimize the design of in situ experiments aimed to
reconstruct fine-scale ocean currents (~20 km), such as those that will be
conducted to validate the first available tranche of SWOT data. A set of
Observing System Simulation Experiments are developed to evaluate different
sampling strategies and their impact on the reconstruction of fine-scale sea level
and surface ocean velocities. The analysis focuses (i) within a swath of SWOT on
the western Mediterranean Sea and (ii) within a SWOT crossover on the subpolar
northwest Atlantic. From this evaluation we provide recommendations for the
design of in situ experiments that share the same objective. In both regions of
study distinct strategies provide reconstructions si.....
