This dataset provides the Greenland ice sheet model output produced as part of the Ice Sheet Model Intercomparison Project for CMIP6 (ISMIP6, Eyring et al., 2016; Nowicki et al. 2016). These simulations focus on 21st century evolution of the Greenland ice sheet under selected CMIP scenarios (RCP2.6, RCP8.5, SSP126 and SSP585) and CMIP models. Results of ISMIP6-Projection-Greenland have been published in Goelzer et al. (2020) and Payne et al. (2021). See here and Nowicki et al. (2020) for the experimentalprotocol, CMIP models, forcing datasets and requested model output data. The ocean forcing datasets are also described in Slater et al. (2019, 2020).The sampling methodology for the CMIP5 models (MIROC5, NorESM, HadGEM2-ES, IPSL-CM5-MR, CSIRO-Mk3.6, ACCESS1.3) is described in Barthel et al. (2020). As CMIP6 models became available, ISMIP6 prepared dataset for CNRM-CM6 (SSP585 and SSP126), CESM2 (SSP585) and UKEM1-CM6 (SSP585). Unlike for the rigorous analysis for the CMIP5 models, the CMIP6 models were selected because of their availability.The forcing dataset is also available via GHub. To view available experiments and individual ice sheet modelcontributions see the summary table in the attached documentation. This archive only contains time varying 2D variables (see Table A1 of ISMIP6 wiki).The data have been conservatively interpolated to a 5km grid by ISMIP6. Polar stereo-graphic projection with standard parallel at 70° N and a central meridian of 45° W (315° E) on datum WGS84 (EPSG3413 projection). The lower left cell center is at (-720000m,-3450000m) with nx=1681 and ny=2881 cells in x and y-direction at full km positions (xmin = -720 km, xmax = +960 km, ymin = -3450 km, ymax = -570 km). The original submission from modeling groups are available upon request by emailing ismip6-at-gmail.com. A brief overview of participating models and characteristics is shown in the table below (see Goelzer et al. 2020).
