A set of well calibrated spring tidal gravimeter measurements in Central Europe and worldwide superconducting gravimeter observations from the Global Geodynamics Project (GGP) are compared with O1 and M2 model computations using the Dehant, Defraigne and Wahr (1999) body tide model and the latest global ocean tide models. For 01, the GGP measurements from different stations show a larger spread in the observed - model results for the in-phase component than for the out of phase (quadrature) component. This is attributed to calibration errors of up to ±0.3% at some of the GGP stations. This precludes further interpretation of the results in terms of lateral heterogeneities or inelastic body tide models. The phase lags of the gravimeters now appear to be well determined, which means that the out of phase components can provide useful tests of the ocean tide models.
