Coupled Model Intercomparison Project Phase 6 (CMIP6) data sets. These data includes all datasets published for 'CMIP6.HighResMIP.ECMWF.ECMWF-IFS-LR' according to the Data Reference Syntax defined as 'mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version'.
The Earth System Model ECMWF-IFS-LR (50 km atmosphere and 100 km ocean), released in 2017, includes the components:
atmos: IFS (IFS CY43R1, Tco199, cubic octahedral reduced Gaussian grid equivalent to 800 x 400 longitude/latitude; 91 levels; top level 0.01 hPa), land: HTESSEL (as implemented in IFS CY43R1), ocean: NEMO3.4 (NEMO v3.4; ORCA1 tripolar grid; 362 x 292 longitude/latitude; 75 levels; top grid cell 0-1 m), seaIce: LIM2 (LIM v2; ORCA1 tripolar grid; 362 x 292 longitude/latitude).
The model was run by the European Centre for Medium-Range Weather Forecasts, Reading RG2 9AX, UK (ECMWF) in native nominal resolutions: atmos: 50 km, land: 50 km, ocean: 100 km, seaIce: 100 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 the results will undoubtedly be relied on by 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 at 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 World Data Centre for Climate (WDCC) at DKRZ.
The project includes simulations from about 90 global climate models and around 40 institutions and organizations worldwide. - Project website: https://pcmdi.llnl.gov/CMIP6.
