The Love number h2 is determined at the M2, N2, O1, and K1 frequencies by combining satellite altimetry with in situ ocean tidal measurements. Topex/Poseidon altimetry is used to measure the (ocean+earth) tide, while gauges at 114 island and ocean-bottom sites determine the ocean tide; the difference sets constraints on h2. Our h2 standard errors are somewhat larger than recent VLBI estimates, but they clearly delineate the resonance in K1 at the 6-&sgr; level. ¿ American Geophysical Union 1995
