SWOT Observations of the Mode-1 M2 Internal Tides in the Southern Ocean

This dataset contains estimates of mode-1 $M_2$ internal tides in the Southern Ocean, derived from the Surface Water and Ocean Topography (SWOT) satellite during its Calibration/Validation (Cal/Val) phase (April to July 2023). These data support the results and reproducibility of figures presented in the manuscript submitted to Journal of Geophysical Research: Oceans. The dataset includes: Regional snapshots of Sea Surface Height Anomaly (SSHA) in SWOT data Estimates of mode-1 M2 internal tides (amplitudes, phases, and propagation directions), as well as uncertainties of amplitudes and phases using plane-wave-fit technique in the Southern Ocean using SWOT data Processed data comparing SWOT-derived estimates against the High-Resolution Empirical Tide (HRET) model. Global maps of empirical mode-1 M2 internal tide parameters derived from stratification climatology, including phase speed, group speed, wavelength, ratio of surface amplitude to max interior amplitude, ratio of depth-integrated energy to surface amplitude squared, ratio of depth-integrated energy flux to surface amplitude squared Data are provided in NetCDF format.
