CMIP6 Recommendation on Regridding
CMIP6 Guidance on Output Grids - their recommendation as to what grid to use while regridding can be found in https://goo.gl/1oA7bO
Previously (April 2017) assembled list of E3SM variables and corresponding CMIP6 variable /wiki/spaces/SIM/pages/126619210 and in particular check
- Note: this is just a check on what CMIP is requesting and which ones we can output if we want to honor the CMIP6 request:
- Spreadsheet of CMIP variables with ACME field and units columns added (col. G,H) for ATM and LND variables
- Sorted version of spreadsheet: Variables not provided by ACME are at the top, with None in red font.
