Research direction
Start by comparing experiment 343 with experiment 341, then inspect the SourceMods/src.cam/air_composition.F90 file and the user_nl_cam configuration described in the issue. The work is complete when the 343 case includes that SourceMods change and EFIX is added to fincl1, with the resulting diagnostics available for comparison.
Written by the indexing model from the issue text.
Description
Purpose:
To support new dynamical cores that use discrete total energy definitions different from CAM physics, we configured the total energy fixer to enforce energy consistent with the dynamical core. This required scaling the physics tendencies in the physics-dynamics coupling layer — and there was a convoluted bug in that scaling!
There are two experiments:
- 343 = "the hammer" - changed dycore to use physics energy (no leaks associated with energy definition)
- 344 = bugfix in CAM7 approach to energy
This is 343
Description:
Same as 341 except:
- add SourceMods
