Abstract
The ACCESS-NRI and Cryosphere Modelling Working Group recently completed an exercise to select an ice sheet model to include within the ACCESS model suite with the primary objective of facilitating decadal- to centennial-scale projections of sea level rise and climate change. Here, we outline the three phase, purpose-driven approach developed, which ultimately led to the selection of the Ice-sheet and Sea-level System Model (ISSM). ISSM is a finite-element thermomechanical ice sheet model that solves the full Stokes equations of momentum balance on an adaptive, anisotropic mesh, and has been widely applied across Antarctic, Greenland, and glacier domains. We outline some of the key capabilities of ISSM, highlighting some case studies from Australian-based users.
