post5.4: Use the correct C13/C14 atm ratio in the code more
Description of changes
This brings in changes to use the correct C13/C134 atmospheric ratio more. I need a scientist working in the C13/C14 space to review this.
Specific notes
Contributors other than yourself, if any:
CTSM Issues Fixed (include github issue #): Fixes #3567
Are answers expected to change (and if so in what way)? Yes, when C13/C14 on for BGC simulations
Any User Interface Changes (namelist or namelist defaults changes)? No No
Does this create a need to change or add documentation? Did you do so? No No
Testing performed, if any: Limited so far
I can review this, Erik. We may be more productive going through this together, or doing a functional test of the code (historical simulation) to see if things look as expected?
