On 18 February 2020, we announced that due to a technical issue, access to download Glaciers elevation and mass change data from 1850 to present from the Fluctuations of Glaciers Database from the Climate Data Store was temporally disabled.
We are pleased to inform our users that full access to this data has been restored and data can be downloaded again from the Climate Data Store.
