The Love number h 2 is determined at the M 2 , N 2 , O 1 , and K 1 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 h 2 . Our h 2 standard errors are somewhat larger than recent VLBI estimates, but they clearly delineate the resonance in K 1 at the 6‐σ level.
