Terrestrial height anomalies are compared with anomalies derived from Global Geopotential Models (GGMs) developed within the GOCO initiative. The analysis examines the influence of epoch differences on geometric heights. Terrestrial anomalies are determined from ellipsoidal heights obtained by GNSS and from precise levelling data. Ellipsoidal heights from 2005 are adjusted to the reference epoch 2025 using a velocity field derived from the European Permanent Network. The results indicate regional subsidence of about −1 mm per year. After temporal harmonization, root-mean-square of differences between terrestrially determined anomalies and those derived from GGMs is approximately 0.21 m for satellite-only models and 0.11 m for combined GGM.
