CMIP6 data conversion tables

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 with input from domain exports. 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.
