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 experiment with longwave cloud-radiative effects off" (amip-lwoff) experiment. These are available at the following frequencies: Amon, LImon, Lmon, 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).

Citable as:  National Center for Atmospheric Research (2020): WCRP CMIP6: National Center for Atmospheric Research (NCAR) CESM2 model output for the "amip-lwoff" experiment. Centre for Environmental Data Analysis, date of citation.
