Outputs used in: Delhasse, A., Beckmann, J., Kittel, C., & Fettweis, X.: Coupling the regional climate MAR model with the ice sheet model PISM mitigates the melt-elevation positive feedback, The Cryosphere Discuss. [preprint], https://doi.org/10.5194/tc-2023-15, in review, 2023. MAR-PISM coupling experiments outputs over 1991-2200. The main experiments are: MAPI-2w: 2-way coupling, consideration online of the melt-elevation feedback (evolving topography in MAR). MAPI-1w: 1-way coupling, consideration of the melt-elevation feedback only with the offline correction (Franco et al. , 2012) of the MAR outputs (fixed topography in MAR). MAPI-0w: 0-way coupling, no consideration of the melt-elevation feedback (fixed topography in MAR and no correction during interpolation). MAR files contain yearly SMB (surface mass balance) and ST (surface temperature) interpolated (with correction) on the PISM-4.5km grid. Gradients used for the correction of the melt-elevation feedback are also given for both variables. SMB and ST are the two required MAR fields to couple MAR with PISM. PISM files contain yearly ice thickness (THK) and ice mask (MASK) as simulated by PISM for each of the three experiments. The MAR code used in this dataset is tagged as v3.11.3 on https://gitlab.com/Mar-Group/MARv3# (last access: 23 January 2024) (MARTeam, 2024). The PISM code used is tagged as PISMv1.2.2 on https://github.com/pism/pism/releases/tag/v1.2.2 (last access: 23 January 2024). Other coupling scripts are also available upon request by email ( [e-mail] ). If you need other variables from MAR or PISM, send us an email ([e-mail], [e-mail])and we will be glad to help you.We will also be happy to share the scripts we have developed to analyse the outputs and make the figures in this paper if needed.
