ISMIP6 Greenland Ice Sheet Projections: Multi-Model Ensemble for Sea-Level Rise

Heiko Goelzer and collaborators provide processed model output from the ISMIP6 (Ice Sheet Model Intercomparison Project for CMIP6) multi-model ensemble study of the Greenland ice sheet. The dataset contains projections of the ice sheet's future contribution to sea-level rise, with results calculated over a 5x5 km grid covering the ice-covered area of Greenland. It supports analysis of model differences under various climate scenarios, with contributions from peripheral glaciers and ice caps removed.

Use Cases

• Projecting future sea-level contribution from the Greenland ice sheet based on multi-model ensemble outputs.
• Comparing ice sheet model performance under different climate forcing scenarios (exp* experiments).
• Analyzing spatially distributed ice mass changes using regridded 5x5 km geospatial data.
• Benchmarking new ice sheet model results against the ISMIP6 ensemble study control experiments.

Strengths

• Data is derived from a multi-model ensemble involving numerous international research groups, as cited in the associated Cryosphere publication.
• Results are processed on a standardized 5x5 km ISMIP6 grid with map projection and ice density corrections applied.
• The dataset explicitly removes the contribution of peripheral glaciers and ice caps for focused analysis of the main ice sheet.

Limitations

• Key metadata such as row count, file size, specific column/variable names, and last update date are unavailable across all platform entries.
• The dataset's structure and specific variables are only partially described, with details cut off in the provided descriptions.
