TEMPO microphysics for WRF

[AndersJensen-NOAA]

Addition of TEMPO microphysics

TYPE: new feature

KEYWORDS: Microphysics, Operational models

SOURCE: Anders Jensen NOAA/GSL

DESCRIPTION OF CHANGES:
Problem:
Microphysics development of a Thompson-Eidhammer based scheme for operational applications has advanced to a submodule, TEMPO. This new development should be made available to WRF users.

Solution:
Connect TEMPO to WRF. A cleaned and refactored version of TEMPO is being tested in the UFS community's MPAS. Additionally, a PR, MPAS-Dev/MPAS-Model#1393, to add TEMPO to NCAR's MPAS is in progress. This current PR will allow the community to use this same microphysics across the UFS, MPAS, and WRF.

ISSUE: For use when this PR closes an issue.

LIST OF MODIFIED FILES:
M .gitmodules
M main/depends.common
M Makefile
M phys/Makefile
M clean
M phys/module_physics_init.F
M phys/module_microphysics_driver.F
M Registry.EM_COMMON

TESTS CONDUCTED:

1. compiled and ran em_quarter_ss
2. restart test with em_quarter_ss
3. bit-for-bit with different number of processes using em_quarter_ss.
4. Passed regression tests.

RELEASE NOTE: Include a stand-alone message suitable for the inclusion in the minor and annual releases. A publication citation is appropriate.

NOTE:
Before this PR is merged, this branch of TEMPO will be merged into the main branch of the authoritative TEMPO repository, https://github.com/NCAR/TEMPO

@AndersJensen-NOAA Can you compile your code on your system with manage_externals? It is showing some errors doing the regression tests.

@weiwangncar I think that I have the code now working with manage_externals pulling a specific tag of TEMPO.

Actually, maybe not. Thanks for the email though -- I will check things again. Note that this compiles on my machine, but the regression tests are still failing.

The regression tests have passed:

Output from dmpar compile with intel and em_quarter_ss case with 1 versus 4 processors
Simulation time = 1 hour with output every 30 mins
Last timestep timing information:
4 processors: 0.05787 elapsed seconds
1 processor: 0.14520 elapsed seconds

Restart test: em_quarter_ss case, 2-h simulation with restart files written every hour compared to 1-h simulation started from a restart file at 1 hour:

@AndersJensen-NOAA Thanks for doing these tests!

[dudhia]

Do you want this to point to your own fork?

[dudhia]

I assume this will be switched when you have merged it into the authoritative repo.

[AndersJensen-NOAA]

@weiwangncar and @dudhia I will switch this to NCAR/TEMPO next week. I need to push my microphysics changes frist.

[weiwangncar]

@AndersJensen-NOAA Can you add a brief summary of the improvement made in this scheme in the PR message? Can you also add a short description for the RELEASE NOTE section - this section will be pulled out to make the Release Notes. You also have a note at the end of the PR: Before this PR is merged, this branch of TEMPO will be merged into the main branch of the authoritative TEMPO repository, https://github.com/NCAR/TEMPO. Has it happened?

[dudhia]

Might consider making it option 48 instead of 88, to keep it within the lower numbers.

@weiwangncar I will work on a list of Bug fixes/improvements. I can do the change to NCAR/TEMPO next week.
