  • A 5 year sample of the CMIP6 ocean data has been setup on NERSC under /global/homes/s/sbaldwin/scratch/cmip_sample/CMIP6/CMIP/E3SM-Project/E3SM-1-0/piControl/r1i1p1f1/Omon
  • The raw ocn and sea-ice data have been set up at /global/homes/s/sbaldwin/scratch/cmip_sample/raw.
  • The sea-ice data is available alongside the rest of the data at /global/homes/s/sbaldwin/scratch/cmip_sample/CMIP6/CMIP/E3SM-Project/E3SM-1-0/piControl/r1i1p1f1/SImon
