Structure and Performance of GFDL’s CM4.0 Climate Model

Friday, Nov 8, 2019

A new a paper led by a team of GFDL and Princeton researchers describes GFDL’s latest multi-purpose atmosphere-ocean coupled climate model, CM4.0. It consists of GFDL’s newest atmosphere and land models at about 100 km horizontal resolution, and ocean and sea ice models at roughly 25 km horizontal resolution. A handful of standard experiments have been conducted with CM4.0 for participation in the Coupled Model Inter-comparison Project Phase 6 (CMIP6), an archive of climate model results utilized by the Intergovernmental Panel on Climate Change (IPCC) and the climate research community more generally.  The paper was published recently in the Journal of Advances in Modeling Earth Systems (JAMES).
