Climate Research: Advancing Earth System Models

  • Code: ACME
  • Science Domain: Climate Science
  • PI: David Bader, Lawrence Livermore National Laboratory


A collaboration among US Department of Energy laboratories and Colorado State University aims to adapt its ACME code to next-generation supercomputers, with a goal of providing new insights related to the effects of climate change. Current work is focused on coupling components for atmosphere, land, ocean, sea and land ice, and river transport. New approaches leveraging Summit’s GPU accelerators will allow researchers to better capture hydrological processes, notably critical land-ice interactions along the coasts of Greenland and Antarctica and complex convective cloud systems. The high-resolution models coupled with better physical representations of sub-grid scale processes will help scientists predict long-term changes in precipitation patterns and future sea-level rise.
