Global ocean tide models on the eve of Topex/Poseidon
- NASA/Goddard Space Flight Center, Greenbelt, MD (United States)
Some existing global ocean tide models that can provide tide corrections to Topex/Poseidon altimeter data are described. Emphasis is given to the Schwiderski and Cartwright-Ray models, as these are the most comprehensive, highest resolution models, but other models that will soon appear are mentioned. Differences between models for M[sub 2] often exceed 10 cm over vast stretches of the ocean. Comparisons to 80 selected pelagic and island gauge measurements indicate the Schwiderski model is more accurate for the major solar tides, Cartwright-Ray for the major lunar tides. The adequacy of available tide models for studying basin-scale motions is probably marginal at best. The subject, however, is in a state of flux, and one may expect rapid advancement over the next several years.
