Omon variable conversion table
Jun 20, 2019
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

| @Luke Van Roekel (Unlicensed) | 7/23/2019 | Values are close, metadata looks good | values compare to 4th decimal with my code, also if I load masso and divide by 1026.0 it matches my MPAS result to 8 decimals but volo only to 4 decimals. Not sure what the difference is. |
