These data include the subset used by IPCC AR6 WGI authors of the datasets originally published in ESGF for 'CMIP6.CMIP.MPI-M.ICON-ESM-LR.piControl' 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 ICON-ESM-LR climate model, released in 2017, includes the following components: aerosol: none, prescribed MACv2-SP, atmos: ICON-A (icosahedral/triangles; 160 km; 47 levels; top level 80 km), land: JSBACH4.20, landIce: none/prescribed, ocean: ICON-O (icosahedral/triangles; 40 km; 40 levels; top grid cell 0-12 m), ocnBgchem: HAMOCC, seaIce: unnamed (thermodynamic (Semtner zero-layer) dynamic (Hibler 79) sea ice model). The model was run by the Max Planck Institute for Meteorology, Hamburg 20146, Germany (MPI-M) in native nominal resolutions: aerosol: 250 km, atmos: 250 km, land: 250 km, landIce: none, ocean: 50 km, ocnBgchem: 50 km, seaIce: 50 km.
