Contributors: The dataset was produced by the WGMS with support from members of the scientific community. It is derived from glacier observations published and acknowledged in the WGMS Fluctuations of Glaciers database (https://doi.org/wgms-fog-2026-02-10). A previous gridded product is also available from the C3S Climate Data Store (https://doi.org/10.24381/cds.ba597449).

Description: This dataset of glacier mass change is derived from glacier observations in the WGMS Fluctuations of Glaciers database (https://doi.org/wgms-fog-2026-02-10) with the code at https://github.com/wgms-org/amce. Geostatistical modelling is used to temporally downscale multi-year glacier-wide elevation changes from remote sensing with annual mass-changes from field measurements to produce an annual mass change timeseries for every glacier. The results are then aggregated by region, 0.5° grid cell, and globally.
Spatial coverage: Global
Temporal coverage: Global estimates for hydrological years from 1976 to 2025 AD, regionally back to between 1915 and 1976, depending on regional data availability
