Abstract

The World Climate Research Program (WCRP) Coupled Model Intercomparison Project, Phase 6 (CMIP6) data from the National Center for Atmospheric Research (NCAR) CESM2 model output for the "AMIP" (amip) experiment. These are available at the following frequencies: Amon, CFmon, LImon, Lmon and day. The runs included the ensemble members: r1i1p1f1, r2i1p1f1 and r3i1p1f1.

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).
