Vienna Terrestrial Reference Frame S/X 2020 for VLBI scale study
Description The dataset contains two terrestrial reference frames, S0 and S1, determined from Very Long Baseline Interferometry (VLBI) observations analysed by the Vienna International VLBI Service for Geodesy and Astrometry (IVS) Analysis Center (VIE). Context and methodology S0: 1980.0-2021.0, S/X...

Thus, additional discontinuity intervals have been introduced in the determination of S1 to more accurately account for the climate change-related processes happening in Svalbard. The two reference frames were computed using VieCompy ( Kern et al. 2023 ), a combination software under the umbrella of VieVS (Vienna VLBI and Satellite Software; Böhm et al. 2018 ) written in Python. The corresponding publication with the title Terrestrial Reference Frame Scale Drift Anomalies in VLBI and the Contribution of Ny-Ålesund Radio Telescopes has been submitted to the Earth, Planets and Space Journal. Technical details The dataset contains the position and velocities of 82 VLBI stations and considers the discontinuities in station position of 19 (S0)/20 (S1) stations.
