GlacierMIP is a framework for a coordinated intercomparison of global-scale glacier mass change models to foster model improvements and reduce uncertainties in global glacier projections. It is running as a 'Targeted Activity' under the auspices of the Climate and Cryosphere Project CliC, a core project of the World Climate Research Programme (WCRP).
GlacierMIP3 and its experimental design and protocol were developed in 2020/2021 by Harry Zekollari (chair), Fabien Maussion, Lilian Schuster, Regine Hock and Ben Marzeion.
This repository holds the description of the experimental protocol and other documents relevant for the third phase of GlacierMIP launched in 2021: GlacierMIP3: Equilibration of glaciers under different climate states (GlacierMIP3 - Equi) together with the code for the analysis of the resulting community estimate paper.
All instructions of how to perform the experiments can be found in the GlacierMIP3 protocol. Everything that was necessary for the GMIP3 submission is in the folder 0_experimental_protocol_files. The submission file names and format conventions are described in netcdf file format notebook with some sample files available in the netcdf_templates folder. A list of Frequently Asked Questions (FAQ) on the GlacierMIP3 submission is also available. If you have other questions, or if you'd like to make suggestions about the project, use github issues.

Code for the community estimate paper above is in the following folders with these respective READMEs:
- 0_pre_post_processing documented in README_0_pre_post_processing.md
- A_community_estimate_paper_analysis documented in README_A_community_estimate_paper_analysis.md
- The main figures are currently only available in the manuscript. However, figure variants (figure simplifications of the Fig. 3 worldmap that are useful for presentations and outreach) and variants of Supplementary Fig. 5 are included in this folder.
The regional GlacierMIP3 glacier projections for the different glacier models and experiments are available and documented via the Zenodo dataset (Schuster, Zekollari et al., 2024). In addition, postprocessed data for the community estimate manuscript are included there. The data documentation is also available in README_data.md.
When using this dataset, please cite both the Zenodo dataset and the submitted study above. Note that we are working currently on potentially another study to analyse more the glacier model differences.
