Supporting data for “Measurands, uncertainty and detectability constraints in short-campaign GNSS on the Drygalski Ice Tongue, East Antarctica”

This dataset supports the manuscript “Measurands, uncertainty and detectability constraints in short-campaign GNSS on the Drygalski Ice Tongue, East Antarctica”. It documents 12 GNSS stations and 248 final station-days from the 2025–2026 campaign. The package contains Supplementary Tables S1 and S2; Bernese GNSS processing configuration and station-day quality-control summaries for the 25 campaign sessions; horizontal velocity and apparent Up-component rate results obtained under four stochastic covariance models; the prepared horizontal coordinate series and the Up-component series produced after two alternative tide-removal treatments; representative HectorP 0.1.12 control configurations; and formal fit diagnostics for the two tidal-response metrics. The tested stochastic models are White, Flicker+White, random-walk+White and free GGM+White. They are alternative covariance descriptions applied to the same coordinate series and their estimates are not averaged. For the vertical analysis, the two prepared series correspond to removal of a fitted station-specific harmonic reconstruction and removal based on a fitted regional tide prediction. The included README files and data dictionaries describe the contents, variables and analysis settings.
