Research direction
Start by comparing the cesm3_0_alpha08o sandbox with the experiment branch and the listed SourceMods files, air_composition.F90 and physpkg.F90. Review user_nl_cam, especially the EFIX diagnostic, then inspect the available run output and diagnostics for experiment 344. Done should mean the energy-fixer scaling behavior is validated for this CAM7 approach.
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 run is 344
Description:
Same as 341 except:
- add SourceMods
