Root mean square (rms) about mean of GPS / levelling minus gravity field model derived geoid heights [m]

The following table shows a comparison of quasigeoid heights derived from the models with GPS / levelling derived geoid values from USA, Canada, Europe, Japan and Brazil. Note that the differences also contain the cut-off error of the models, i.e. the unmodelled short wavelength part of the gravity field. The GPS / levelling data sets are from:
