Derived datasets for the 2025–2026 surge of Dehdal Glacier (Pamir Mountains, Tajikistan)

This dataset includes derived data for analysing the 2025–2026 surge of Dehdal Glacier in the northwestern Pamir Mountains, Tajikistan. It features glacier outlines mapped from high-resolution PlanetScope imagery, glacier surface velocity data, a flowline time series used to reconstruct surge propagation, regional climate observations, and an earthquake catalog for the surrounding area. These data support the reconstruction of the surge–detachment sequence and the analysis of environmental controls on glacier instability presented in the associated research article.Dataset Contents Glacier outlines digitised from PlanetScope imagery during the 2025 surge event. Annual and short-term glacier velocity datasets. Flowline time series depicting the propagation of the surge front. Regional climate observations from 2016 to 2025. Earthquake catalogue for the Dehdal Glacier region.
