A new empirical model of ocean tides has been developed for the Weddell Sea, south of 668S, between 908W and 08, using six years of radar altimeter data from the CryoSat-2 satellite mission. Because of its long groundtrack repeat period (368 days) and its diverse measurement modes, low-rate mode (LRM) over the ocean and synthetic aperture radar interferometric mode (SARin) over ice surfaces and parts of the ocean, the CryoSat2 data pose a number of challenges for tidal analysis. The space and time sampling properties of the exact repeat, near-repeat, and crossover ground tracks have been analyzed to discover which …
