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 "abrupt doubling of CO2" (abrupt-2xCO2) experiment. These are available at the following frequencies: Amon, LImon, Lmon, Ofx, day and fx. 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.
