A global combined GNSS velocity field with almost 13,400 sites has been derived by the International Association of Geodesy’s Joint Working Group 3.2. The combined field is aligned to the ITRF2020 and gathers global and regional velocity fields computed by nineteen groups using different approaches. In addition to the combined velocities and their uncertainties, the combination also provides the alignment of each velocity field to the ITRF2020, the scaling of their velocity uncertainty and the estimated repeatability of the velocity estimates across the different groups at almost 3,000 sites. The median repeatability is at the level of 0.17 and 0.27 mm/yr for the horizontal and vertical velocities. Up to 11 % of the sites show poor velocity repeatability exceeding 3 times the median values.
