This is a working document showing the conversion status for publishing E3SM data to CMIP6. The variables listed are unordered, and pulled from the priority 1 request list as well as scientist input. If you think that an important variable is missing please add it.
The conversion formulas are for the most part compiled by a NON DOMAIN EXPERT (me) using the following resources. There is the very real possibility they may be incorrect, please verify the conversions in your area of expertise and mark the "verified" column with your name.
Much of this information is pulled from the previous discussion page E3SM data conversion for CMIP6, but I wanted to distill the information down to the bare necessities.

- CESM Amon conversion table for CMIP5 (https://github.com/NCAR/CCP_Processing_Suite/blob/master/CMOR2/Xwalks/xwalk_CMIP5_Amon, thanks to Peter Caldwell for finding this).
- All fields must be interpolated in the horizontal to the new CMIP6 grids for which Charlie Zender prepared mapping files.
- Some 3d variables must be reported on model levels and others interpolated to the standard 19 pressure levels.

Can we approximate TOA with TOM?
NCAR used FSNTOA-FSNT+FLNT

Additional tables to consider
- 3hr, 6hrLev, 6hrPlev, 6hrPlevPt
- CF3hr, CFday, CFmon (suggest consulting with Yuying Zhang on most useful variables and variables not impacted by COSP bug).
- AERmon
