Atmospheric and oceanic forcing for the Greenland Ice Sheet, prepared for ISMIP7. Downscaled from CESM2-WACCM and MRI-ESM2-0 for the ctrl and historical periods and the ssp126, ssp245, ssp370, ssp534-over and ssp585 scenarios, at 1 km and 4 km by three downscaling methods (SDBN1, GEMB-SDBN1 and dEBM2), together with ocean thermal forcing and salinity at 1 km and 4 km, and OCX reanalysis-driven forcing from RACMO2.3p2-ERA and EN4. Mirrored from the ISMIP7 GHub collection at the University at Buffalo, which remains the archive of record.
