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 VLBI sessions with more than 3 stations S1: 1980.0-2021.0, S/X VLBI sessions with more than 3 stations + additional discontinuity breaks for NYALES20 due to PDIM, GIA These terrestrial reference frames were used to calculate session-wise estimated VLBI scale factors to analyse the impact of a modfied station movement model for the VLBI station NYALES20 (Norway, Svalbard) on the VLBI scale. 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 ...
