The data file contains reconstructions for area, mass, and mass change of glaciers on the global scale, as well as the attached model uncertainties, from 10 model runs, each forced by a different meteorological reanalysis data set. All model setups were statistically optimized regarding the ability to reproduce glaciological mass-balance measurements. The values are specified by regions, following the region definition of the Randolph Glacier Inventory (https://www.glims.org/RGI/). Values are given annually for the years 1901 to 2018, though for the individual model runs they are only given for years in which the respective meteorological data set contains data.
