Simulated length of 71 Alpine glaciers over the last millennium using OGGM

This dataset contains the simulated length of 71 Alpine glaciers over the last millennium using the version 1.0 of the Open Global Glacier Model (OGGM) forced by global climate models (GCM) simulation outputs. For a description of the experimental design, see the associated publication:

Goosse, H., Barriat, P.-Y., Dalaiden, Q., Klein, F., Marzeion, B., Maussion, F., Pelucchi, P. and Vlug, A.: Testing the consistency between changes in simulated climate and Alpine glacier length over the past millennium, Climate of the Past, 2018.

Each NetCDF file corresponds to OGGM driven by one climate model over the period 1000-2004 CE. The file names are based on the acronyms given in the Table 1 of the associated publication. The variables included in the NetCDF files are:

- g_length: Annual mean length of the glaciers, in meters

- ID_glacier: an identifier for each glacier, allowing to make the link to the names of the glaciers given in glacier_names.txt.

- time_year: the time in years CE

In order to remove high frequency variability associated with the presence of snow that may remain in summer at altitudes lower than the glacier front, a filter with a 5-year window has been applied on the OGGM outputs to obtain the results stored in g_length.
