Contributors: The dataset was produced by the WGMS with support from members of the scientific community, as listed below. It builds on glacier observations from in-situ and remotely sensed observations from the WGMS network, which are available and acknowledged in the WGMS Fluctuations of Glaciers database (https://doi.org/10.5904/wgms-fog-2025-02). 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 changes is based on glacier observations from in-situ and remotely sensed observations from the WGMS Fluctuations of Glaciers database. Geostatistical modelling was used for the temporal downscaling of decadal glacier-wide elevation change estimates derived from satellite data with annual mass-change observations from field measurements. The resulting dataset contains the yearly mass-change time series for individual glaciers (CSV files) and the derived global gridded annual mass change product, aggregated at a spatial resolution of 0.5° latitude and longitude (NetCDF-4).

Spatial coverage: Global

Temporal coverage: Global estimates for hydrological years from 1976 to 2024 AD, regionally back to between 1915 and 1976, depending on the regional data availability.
