title: E3SM-Project E3SM2.0 model output prepared for CMIP6 RFMIP piClim-control

description: Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.RFMIP.E3SM-Project.E3SM-2-0.piClim-control' with the full Data Reference Syntax following the template 'mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version'.
 
 The E3SM 2.0 (Energy Exascale Earth System Model) climate model, released in 2022, includes the following components:
 aerosol: MAM4 with new resuspension, marine organics, secondary organics, and dust (atmos grid), atmos: EAM (v2.0, cubed sphere spectral-element grid; 5400 elements, 30x30 per cube face. Dynamics: degree 3 (p=3) polynomials within each spectral element, 112 km average resolution. Physics: 2x2 finite volume cells within each spectral element, 1.5 degree (168 km) average grid spacing; 72 vertical layers; top level 60 km), atmosChem: Troposphere specified oxidants (except passive ozone with the lower boundary sink) for aerosols. Stratosphere linearized interactive ozone (LINOZ v2) (atmos grid), land: ELM (v1.0, satellite phenology mode, atmos grid), MOSART (v1.0, 0.5 degree latitude/longitude), ocean: MPAS-Ocean (E3SMv2.0, EC30to60E2r2 unstructured SVTs mesh with 236853 cells, 719506 edges, variable resolution 60 to 30 km; 60 levels; top grid cell 0-10 m), seaIce: MPAS-Seaice (E3SMv2.0, ocean grid; 5 ice categories; 7 ice, 5 snow layers). 
The model was run by the LLNL (Lawrence Livermore National Laboratory, Livermore, CA 94550, USA); ANL (Argonne National Laboratory, Argonne, IL 60439, USA); BNL (Brookhaven National Laboratory, Upton, NY 11973, USA); LANL (Los Alamos National Laboratory, Los Alamos, NM 87545, USA); LBNL (Lawrence Berkeley National Laboratory, Berkeley, CA 94720, USA); ORNL (Oak Ridge National Laboratory, Oak Ridge, TN 37831, USA); PNNL (Pacific Northwest National Laboratory, Richland, WA 99352, USA); SNL (Sandia National Laboratories, Albuquerque, NM 87185, USA). Mailing address: LLNL Climate Program, c/o David C. Bader, Principal Investigator, L-103, 7000 East Avenue, Livermore, CA 94550, USA (E3SM-Project) in native nominal resolutions: aerosol: 100 km, atmos: 100 km, atmosChem: 100 km, land: 100 km, ocean: 50 km, seaIce: 50 km. 

Project: These data have been generated as part of the internationally-coordinated Coupled Model Intercomparison Project Phase 6 (CMIP6; see also GMD Special Issue: http://www.geosci-model-dev.net/special_issue590.html). The simulation data provides a basis for climate research designed to answer fundamental science questions and serves as resource for authors of the Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC-AR6).

CMIP6 is a project coordinated by the Working Group on Coupled Modelling (WGCM) as part of the World Climate Research Programme (WCRP). Phase 6 builds on previous phases executed under the leadership of the Program for Climate Model Diagnosis and Intercomparison (PCMDI) and relies on the Earth System Grid Federation (ESGF) and the Centre for Environmental Data Analysis (CEDA) along with numerous related activities for implementation. The original data is hosted and partially replicated on a federated collection of data nodes, and most of the data relied on by the IPCC is being archived for long-term preservation at the IPCC Data Distribution Centre (IPCC DDC) hosted by the German Climate Computing Center (DKRZ).

The project includes simulations from about 120 global climate models and around 45 institutions and organizations worldwide. - Project website: https://pcmdi.llnl.gov/CMIP6.
