Observing the Ocean Surface Topography at High Resolution: Opportunities and Challenges for the Future SWOT Mission I
Session ID#: 92542
Session Description:
The future altimetry international Surface Water and Ocean Topography (SWOT) Mission to be launched in 2021 will make high-resolution 2D observations of sea-surface height (SSH) using SAR radar interferometry techniques at an unprecedented resolution of 15-40 km wavelength, depending on sea state conditions. These observations, with about one order of magnitude higher resolution than current altimetry products, will provide new opportunities to study the fine scale oceanic dynamics as well as internal tides and internal waves, and their role in connecting the interior of the ocean to the upper layer. The SWOT mission will be divided in two phases on different orbits. The first âfast sampling phaseâ is dedicated to mission calibration and science validation and will have a reduced spatial coverage but an enhanced temporal resolution (daily, and twice a day over track crossovers). The second phase (the nominal one) will map the entire earth up to 77.6° latitude, sampling a given location 2-6 times every 21 days. This session will explore recent studies in understanding how fine scale SSH dynamics are linked to the sinks, sources and stirring of kinetic energy in the ocean, and to their related ecological and biogeochemical processes. The session encourages modeling and assimilation approaches, as well as studies of the in-situ or airborne experimental strategies to be deployed to observe these small-scale, rapidly evolving dynamics during both the fast sampling and the nominal phases.
