Development of Barotropic and Baroclinic Tide Models in Support of the SWOT Mission
PI: Richard Ray (08-Feb-18). First-mode baroclinic tides have typical wavelengths in the deep ocean of order 100-170 km for semidiurnal tides, double that for diurnal tides. Higher modes have shorter scales. These tides thus fall directly into the prime mesoscale and submesoscale regime that SWOT is designed to study. It will be critical to remove as much of this tidal variability in SWOT data as possible. Our project aims to develop both barotropic and baroclinic tidal models to support this goal and to deliver models to the SWOT project teams that can be employed for the initial processing of SWOT data.
Tides and the SWOT Mission: Transition from Science Definition Team to Science Team
Arbic, B.K., Lyard, F., Ponte, A., Ray, R.D., Richman, J.G., Shriver, J.F., Zaron, E.D., and Zhao, Z. (00-Jan-15). In this document, we briefly review the progress-to-date, and work remaining, on shelf tides, coastal tides, open-ocean internal tides, and high-latitude tides as they pertain to the SWOT mission. In addition, we also discuss plans for tidal correction algorithms, the need for better bathymetry, especially in coastal regions, and the need for a coordinated effort to evaluate tidal models. Finally, we conclude with some recommendations for SWOT-related tide model development efforts.
