Description
Summary:Here we present the sensitivity experiments are conducted with the latest GRISLI version 2.0 (Quiquet et al. 2018), to model changes of the Antarctic ice sheet between 100 ka and 400 ka. GRISLI 2.0 is is a large-scale three-dimensional thermomechanical ice sheet model and the newest version of the Grenoble Ice Sheet and Land Ice model (Ritz et al. 2001). The model combines an inland ice model with an ice shelf model, extended to the case of ice streams considered as dragging ice shelves. The latest release includes a better representation of grounding line migration and a sub-glacial hydrology model. The model uses finite differences on a Cartesian grid at 5 to 40 km resolution depending on the application. Here we use a 40 km grid. The spatial coverage of the model experiments is latitude: -90/-54.6602 longitude: -180/180. For the selection of the ice sheet model parameters, we used the calibration performed in Quiquet et al. (2018) using the ensemble member labeled AN40T213 in Quiquet et al. (2018). This ...
