The World Climate Research Program (WCRP) Coupled Model Intercomparison Project, Phase 6 (CMIP6) data from the Geophysical Fluid Dynamics Laboratory (GFDL) GFDL-CM4 model output for the "AMIP SSTs with 4xCO2" (amip-4xCO2) experiment. These are available at the following frequencies: Amon, CFday, CFmon, LImon, Lmon and day. The runs included the ensemble member: r1i1p1f1.

CMIP6 was a global climate model intercomparison project, coordinated by PCMDI (Program For Climate Model Diagnosis and Intercomparison) on behalf of the WCRP and provided input for the Intergovernmental Panel on Climate Change (IPCC) 6th Assessment Report (AR6).

The official CMIP6 Citation, and its associated DOI, is provided as an online resource linked to this record.
