The high resolution and wide swath of the SWOT's main instrument KaRIn enables the observation of eddies ten times smaller than previous altimetry missions
A single Swot KaRIn altimeter swath can produce marine gravity data of a quality comparable to that obtained over 20 years of conventional nadir altimetry.
The Mean Sea Surface is one of the reference surfaces computed for, and from, altimetry. Including the geoid, it comprises the effect of undersea reliefs on the gravity field
