This is looking good! A couple of changes (mainly reversing whitespace changes), please. Hopefully all regression tests pass on Hera with both compilers.

This looks good to me, thanks for updating the formatting. I will combine this PR with other PRs, so that you don't have to keep updating the PRs from main all the time.

climbfuji · 2021-07-23T14:35:51Z

@mzhangw I just discovered that the changes in your PR lead to situations where you are passing the SAME variable (i.e. same standard name) to the scheme twice with different local name. That is forbidden, not just by CCPP but also by Fortran standards. See for example sfc_nst and sfc_drv_ruc. I'll fix that in my effort to bring it up to date with the current code and combine it with Xia's changes.

climbfuji · 2021-07-23T14:47:26Z

I also get those errors from the host model variable definitions:

ERROR: Multiple definitions of standard_name surface_longwave_emissivity_over_ice in type/variable defintions

Will work on it.

I actually don't understand how this code compiled, ran and verified against the existing baselines. The metadata parser immediately threw errors about duplicate standard names in several ccpp-physics routines. I don't remember adding this check recently, but maybe I did.

mzhangw · 2021-07-23T17:30:59Z

It did pass all RTs a while ago. I will take a look at it again today if it is ok with you. Sitting at Dr. office now.

Recent code update causes some conflicts with this PR. I need revisit this PR.

climbfuji · 2021-07-29T14:53:44Z

Thanks, agreed. The code should never have compiled or run. Passing the same variable twice to a subroutine is dangerous and can have bad consequences. This PR is therefore on hold until the issues are resolved. Thanks for working on it, and sorry for not catching the problems in the first review (GitHub diff view isn't any good for this type of changes).

mzhangw · 2021-07-29T15:08:01Z

The PRs did pass all RTs back in May (See my attached log). However, the surface codes have been updated significantly since then. It won't hurt to revisit it with new updates.

Even if they passed, the code was incorrect. You are not allowed to pass the same variable (e.g. same standard name) twice to a Fortran function or subroutine. Fortunately, the CCPP framework now catches these errors.
