This repository contains annual 3D sea water age since surface contact files from the ScenarioMIP ssp585 simulation conducted with GFDL's ESM4.1 climate model (Dunne et al., 2020) that was contributed to the 6th Coupled Model Intercomparison Project (CMIP6). Both the ocean model native grid and the regridded output can be found in this repository. For the regridded output, the files have been regridded from MOM6 native grid to standard World Ocean Atlas 1x1 horizontal grid, and they have been remapped from the lagrangian vertical coordinate used by GFDL's MOM6 ocean model (Adcroft et al., 2019) to standard World Ocean Atlas depths. Files have undergone QA/QC. All data files are NetCDF. Enquiries should be directed to Jasmin.John (Jasmin.John@noaa.gov) or John Dunne (John.Dunne@noaa.gov) Anyone using these data should cite Dunne et al. (2020) and Adcroft et al. (2019). See references below. Other variables associated with these simulations, along with assigned DOI's, are available through the ESGF CMIP6 portal: https://esgf-node.llnl.gov/projects/cmip6/ ______________________________________________________________________ The organization of this repository is as follows: Experiments: The tar files in the repository follow this naming convention: <model>_<activity>_<MIP>_<experiment>_<component_and_grid>_<variable>.tar.gz E.g. GFDL_ESM4_CMIP6_ScenarioMIP_ssp585_ocean_annual_z_1x1deg_agessc.tar.gz (regridded) GFDL_ESM4_CMIP6_ScenarioMIP_ssp585_ocean_annual_z_agessc.tar.gz (native grid) The organization of above repository is as follows: Experiment: ssp585 NOAA-GFDL/CMIP6/ScenarioMIP/GFDL-ESM4/ESM4_ssp585_D1/ For each experiment, 3D annual sea water age data can be found in the sub-directory: /ocean_annual_z_1x1deg (for regridded output) /ocean_annual_z (for native grid output) _________________________________________________________________________ NOTES: Provenance: The data provided here do not have metadata that can be used for provenance and traceability back to NOAA/GFDL. The data DOI assigned should be used when sharing and citing these data. _________________________________________________________________________
