Bringing ice sheets to life: Releasing a dynamic ice sheet modeling workflow for Australia's climate model
Ice sheets are fundamental components of the Earth system. Antarctica and Greenland, the two ice sheets currently on Earth, don't just affect their own regions: What happens on these vast masses of land ice influences weather, climate, society and the environment around the planet.
Ice sheets, such as those in Antarctica and Greenland, have a significant impact on global weather, climate, society, and the environment. The Ice Sheet and Sea-level System Model (ISSM) workflow, developed by the Australian National Computational Infrastructure (NCI), aims to integrate a dynamic ice sheet model into the ACCESS climate suite for the first time.
This dynamic model captures the complex interactions between ice, ocean, and atmosphere, which are essential for accurate climate projections. The ISSM workflow consists of four key components that enable researchers to begin using the model without extensive setup. By running on Australian infrastructure, the Australian modeling community can access the same model and data sets, simplifying the process and making it more accessible.
Dr. Mike Tetley, team lead of the Ice Sheet Modeling team at ACCESS-NRI, emphasized the importance of accurately modeling the interactions between ice sheets and the surrounding systems to understand potential climate changes over the coming centuries. The ISSM project is supported by the Australian research community, with plans to expand the model's capabilities, such as regional sea-level fingerprint modeling and a whole-Antarctic ice sheet model configuration.
