What happened? What did you expect to happen?

Hi, I've noticed that GCHP 14.5.0-rc.0 was published on the git, so I wanna give it a try. In the simulation I set by defualt with the restartfile in #431 , the result still remain strange, I'm not sure what is wrong. I post a part of the allPEs.log and other config files below.

What are the steps to reproduce the bug?

Please attach any relevant configuration and log files.

What GCHP version were you using?

14.5.0-rc.0

What environment were you running GCHP on?

Local cluster

What compiler and version were you using?

ifort 2021.3.0

What MPI library and version were you using?

Intel MPI 2021.3.0

Will you be addressing this bug yourself?

Yes

14.5.0 is not validated for the GCHP carbon simulation. See comments in https://github.com/geoschem/GCHP/issues/440 for timeline and suggestions if you wish to debug yourself.

@lizziel Thank you for the information. I was wondering if previous versions, like 13.0.0, are available for GCHP carbon simulations. In #440, I noticed that the bug primarily affects carbon simulations, not full-chemistry simulations. Is that correct?

[lizziel]

Carbon simulations for GCHP are not available prior to 14.4. There is a CO2 w/ fluxes option but this was developed for use with the GCHP adjoint. We will be retiring that simulation once the GCHP carbon fixes are released.

[lizziel]

Yes, the carbon bugs do not affect full chemistry. The full chemistry is thoroughly vetted every release through benchmarking.

I'm glad to hear this, thank you for your help again, @lizziel! Close this issue.
