Data Access Statement: The underlying GPS data are from the POLENET Antarctic network (Wilson et al., 2025) based on services provided by the Geodetic Facility for the Advancement of Geoscience (GAGE), operated by Earthscope, with support from the National Science Foundation (NSF), the National Aeronautics and Space Administration, and the U.S. Geological Survey under NSF Cooperative Agreement EAR-1724794. The processed displacement time series used in this study can be found on a Zenodo archive (Koulali et al., 2025). The SMB model RACMO2.3p1 data set is from van den Broeke (2019). The RACMO2.3p2 data set is from van Wessem et al. (2023). The RACMO2.4p1 model SMB data set is from van Dalum et al. (2024).
