This dataset presents the data from the third phase of GlacierMIP (GlacierMIP3: Equilibration of glaciers under different climate states). It includes regional glacier volume and area projections as submitted by the glacier modelling groups. Additionally, it features post-processed and aggregated data derived from GlacierMIP3, or in combination with other studies, which is used for the analyses and visualisations presented in the following manuscript: Zekollari*, H., Schuster*, L., Maussion, F., Hock, R., Marzeion, B., Rounce, D. R., Compagno, L., Fujita, K., Huss, M., James, M., Kraaijenbrink, P. D. A., Lipscomb, W. H., Minallah, S., Oberrauch, M., Van Tricht, L., Champollion, N., Edwards, T., Farinotti, D., Immerzeel, W., Leguy, G., Sakai, A. (under review): Glacier preservation doubled by limiting warming to 1.5°C. Preprint available at https://doi.org/10.31223/X51T5W, 2024.*Harry Zekollari and Lilian Schuster contributed equally to this dataset and the manuscript above.If you use the data, please cite this Zenodo dataset and the above study. More info in README_data.pdf. For information about the GlacierMIP3 experimental design, please refer to the GlacierMIP3_protocol.pdf. The code used to generate the postprocessed data and to conduct the analyses for the manuscript mentioned above is available at https://github.com/GlacierMIP/GlacierMIP3. To assist potential data users, we have included a jupyter notebook (gmip3_data_example_use_cases.ipynb) that guides you through some simple use cases. This notebook can be directly run when clicking on this link. Please note that you will need to log in to your Google account and, if you haven't already done so, install Google Colaboratory. The data will then be automatically downloaded to your account. We may adapt the data structure and improve the documentation during the review phase. If you have any questions or suggestions, please contact us (lilian.schuster@uibk.ac.at, harry.zekollari@vub.be). ----difference version v2 to v1.0: only the files README_data.pdf and the lowess*_regional_glacier_temp_ch.csv were changed according to the resubmission of the manuscript
