Tables of tidal variations in Earth orientation (both rotation rate and polar motion) are provided for various global oceanic tide models. Most of these tables have been published in one form or another in various journals and reports, but some are unpublished and have been kindly submitted to this site by their authors. Only models that are global, or nearly global, are appropriate for these applications. Moreover, models of both tidal heights and tidal currents are required. The UT1 and polar motion parameters here are deduced from the angular momentum integrals of these models by use of formulæ in Gross (1993).
All tables linked from this page are in the same format. They give components of Universal Time (UT) and polar motion (prograde and retrograde). The components are given in terms of an amplitude and a phase lag, where the phase convention is the standard one used in ocean-tide studies, following Doodson (Doodson and Warburg, 1941). Phases of polar motion are precisely those used by Gross (1993).
