PS005:
Key Ocean Science Opportunities and Challenges from the SWOT Mission


Session ID#: 28177

Session Description:
The Surface Water and Ocean Topography (SWOT) is a joint mission of NASA and the French Space Agency CNES, with contributions from Canada and the UK.  The primary instrument of SWOT is a Ka-band radar interferometer for measuring the elevation of water surface over land and ocean. The oceanographic objectives of the mission are to observe sea surface height (SSH) at scales approaching 15 km, depending on the sea state.  SWOT will make SSH measurement over a swath of 120 km with a nadir gap of 20 km in a 21-day repeat orbit to map the entire ocean with minimal gaps. The increased spatial resolution over conventional altimetry offers an unprecedented opportunity to study fine-scale 2D ocean surface height processes in the open and coastal oceans. The SWOT fine-resolution SSH 2D images will allow us to address important questions about the ocean circulation and its interaction with higher-frequency processes such as ocean tides and internal waves. The session will address the SSH ocean signal at scales of 15-200 km, from modelling, satellite and in-situ studies, including calibration/validation approach. Studies of open ocean dynamics, coastal, estuarine, and sea-ice processes will be encouraged.
