An ice sheet model ensemble of the last deglaciation in the Ross Sea, Antarctica

This dataset contains netCDF output files and make files for 52 simulations of past behavior of the Antarctic Ice Sheet, using the Pennsylvania State University ice sheet model (e.g., Pollard and DeConto, 2012). There are two full-continent simulations at 40 km resolution from 125 kyr BP to present, two full-continent simulations at 20 km resolution from 25 kyr BP to present, and 48 nested simulations over the Ross Sea sector at 10 km resolution from 20 kyr BP to present. The 40 km resolution runs provide the initial conditions for the 20 km resolution runs, and the 20 km resolution runs provide initial and boundary conditions for the 10 km resolution runs. These simulations are presented and discussed by Hillebrand et al. (2021). The model output in the netCDF files can be easily viewed using the ncview tool.
