| Summary: | This dataset provides the Antarctic 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 Antarctic ice sheet under selected CMIP scenarios (RCP2.6, RCP8.5, SSP126 and SSP585) and CMIP models. Results of ISMIP6-Projection-Antarctica have been published in Seroussi et al. (2020) and Payne et al. (2021). See here and Nowicki et al. (2020) for the experimentalprotocol, CMIP models, forcing datasetsand requested model output data. More information on the oceanic datasets is provided in Jourdain et al. (2020).The sampling methodology for the CMIP5 models (NorESM1-M, MIROC-ESM-CHEM, CCSM4, HadGEM2-RS, CSIRO-Mk3, IPSL-CM5A-MR) 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 8km diagnostic grid by ISMIP6. Polar stereo-graphic projection with standard parallel at 71° S and a central meridian of 0° W on datum WGS84. The lower left corner is at (-3040000 m, -3040000 m) and the upper right at (3040000 m, 3040000 m). This is the same grid used to provide the SMB and basal melting anomaly forcings. The original submission from modeling groups are available upon request by emailing ismip6-at-gmail.com. A brief overview of the participating models and their characteristics is shown in the table below (Table 3 of Seroussi et al., 2020) Downloading Data The data can be downloaded from the Globus GHub-ISMIP6-Projectionsendpoint.
