Benchmarking the vertically integrated ice-sheet model IMAU-ICE (version 2.0)
Ice-dynamical processes constitute a large uncertainty in future projections of sea-level rise caused by anthropogenic climate change. Improving our understanding of these processes requires ice-sheet models that perform well at simulating both past and future ice-sheet evolution. Here, we present v...
