Quantifying errors on SWOT sea surface heights in the Southern Ocean ...
The SWOT error budget for sea surface height measurements are predicated on a significant wave height (SWH) of 2 meters. Within this range, the surface wave error on the swath falls below the noise floor, and is assumed it can be ignored. However, there are many locations within the oceans where thi...

The SWOT error budget for sea surface height measurements are predicated on a significant wave height (SWH) of 2 meters.
