WGMS provides standardized observations on changes in mass, volume, area and length of glaciers with time (Fluctuations of Glaciers), as well as statistical information on the distribution of perennial surface ice in space (World Glacier Inventory). In addition, information on special events (e.g., surges, calving instabilities, ice avalanches, lake outbursts) is available. All data and information is freely available for scientific and educational purposes. The use requires acknowledgement to the WGMS and/or the original investigators and sponsoring agencies according to the available meta-information.
Fluctuations of Glaciers
In order to get an overview on available glacier fluctuation series or to search for information of a specific glacier, use the WGMS Fluctuations of Glaciers Browser. The Browser allows you to directly download minimal data series of glacier changes together with corresponding survey and reference years. Full measurement details for individual observation series as well as larger datasets can be ordered by email. The same email can be used to report corrections and new data.
Use the interactive Fluctuations of Glaciers Browser to browse available data for individual glaciers, geographical regions, and measurement types (i.e., front variation, glaciological mass balance, geodetic thickness change):
World Glacier Inventory
For direct access to the World Glacier Inventory (WGI), please visit our mirror-site hosted by the US National Snow & Ice Data Center (NSIDC).
Glacier Special Events
Information on glacier-related special events such as surges, claving activities, rock falls onto glaciers, lake outbursts, ice avalanches, eruptions of glacier-clad volcanoes or related protection work including prospection and scientific analysis are regularly reported and documented in a corresponding Chapter in the Fluctuations of Glaciers publication series.
