About the data:
- The results are based on model output regridded conservatively to a 5x5 km regular ISMIP6 grid unless this is already the native grid. 
- The results are calculated over the ice-covered area of Greenland, map projection error corrected, ice sheet model specific densities taken into account.
- The contribution of peripheral glaciers and ice caps has been removed, by considering their area-coverage in each grid cell.
- The results for the projections 'exp*' are all calculated as differences to the control experiment ctrl_proj (suffix cr in filename for control removed).
- Results for ctrl_proj and historical are un-corrected (no suffix cr in filename).
