The Greenland Ice Sheet Large Ensemble: Future Simulations 2018-2203

### Access Dataset files can be accessed and downloaded via: [https://arcticdata.io/data/10.18739/A2VX0651F/](https://arcticdata.io/data/10.18739/A2VX0651F/). ### Overview This dataset includes NetCDF model output from the Stochastically Enabled version of the Ice-Sheet and Sea-Level System Model (StISSM; Verjans et al. 2022). The domain encompasses the Greenland Ice Sheet. The time period of all large ensemble, and almost all ensemble simulations (except for "branched" small ensembles) extend over the time period 2018-2203. Each NetCDF files includes thickness and velocity on an unstructured finite-element mesh output every year for one simulation. The repository as a whole include two large ensembles (100 member simulations each) and 9 small ensembles (30 member simulations each). All methodological and modeling details of the ensemble are detailed in a pre-print by Verjans, Robel et al. Verjans, V., Robel, A. A., Ultee, L., Seroussi, H., Thompson, A.
