Science Goals
Southern Ocean near-surface current speed from ECCO2.
- Provide sea surface heights (SSH) and terrestrial water heights over a 120 km wide swath with a +/-10 km gap at the nadir track.
- Over the deep oceans, provide SSH within each swath with a posting every 2 km x 2 km, and a precision not to exceed 0.5 cm when averaged over the area.
- Over land, download the raw data for ground processing and produce a water mask able to resolve 100-m rivers and 1-km2 lakes, wetlands, or reservoirs. Associated with this mask will be water level elevations with an accuracy of 10 cm and a slope accuracy of 1 cm/1 km.
- Cover at least 90 percent of the globe. Gaps are not to exceed 10 percent of Earth's surface.
- SWOT will have a mission lifetime of 3 years
