Abstract	The oceanic tidal angular momentum (OTAM) has Been demonstrated to be the primary cause for the diurnal and semidiurnal variations in the Earth's rotational rate, or ∆UT1. Three ocean tide models derived from the Topex/Poseidon altimetry mission are employed to yield predictions of ∆UT1 for eight major diurnal/semidiurnal tides. The predictions are compared with geodetic determinations of ∆UT1 from the very-long- baseline interferometry data both for long-term observations and during intensive campaigns. The agreement is good, with discrepancies typically within 2-3 μs. Systematic discrepancies observed for the well-determined M₂ tide clearly reveal the contribution of the Earth's spin libration.
