Description:

Adds or updates the following ultra-low coupled control (S2SW) configurations:

Test	Status	ATM Res	OCN/ICE Res	WW3 Res	Tasks	RunTime (hera)
cpld_control_c48_5deg	+ WAV	C48	mx500	9km	24
cpld_control_c24_5deg	new	C24	mx500	9km
cpld_control_c24_9deg	new	C24	mx900	9km	13
cpld_control_c12_9deg	new	C12	mx900	9km	13

Warmstarts for each test were generated at [TBD] from the control tests for each resolution and added to the staged input data directory on hera.

New input is located /scratch1/NCEPDEV/stmp4/Denise.Worthen/input-data-20250131 and must be sync'd to all platforms. The date on the input data directory is arbitrary.

Commit Message:

* UFSWM - add control, warmstart and restart-from-warmstart tests for ultra-low resolution configurations. 
* UFSWM - add missing WW3 restarts for fully coupled S2SWAL configuration tests
  * FV3 - add new SDF for low-res physics

Priority:

• Normal

@LarissaReames-NOAA No specific reason, no. I was following the current c48-5degs for the lower resolutions and that original C48-5deg does not include waves.

[LarissaReames-NOAA]

Yeah, understood, that makes sense. Could we give those components a try? If we're going for a plumbing test here, it makes sense that we should include those components.

[DeniseWorthen]

@JessicaMeixner-NOAA I see your comment where to find the 9-deg WW3 files. Do you have similar files available for 5-deg? We're adding a C24-5deg and we could, if desired, update the existing C48-5deg to include waves.

[JessicaMeixner-NOAA]

I only created a 9km. Can we just use that for both tests for now? I wont have time to create a 5km for a while.

[DeniseWorthen]

@JessicaMeixner-NOAA 9km? You mean 9deg I hope ;-)

We're adding C24-5deg and C12-9deg. Are you suggesting using 9-deg WW3 for both? So that it is C24-5deg Ocn/Ice + 9 deg WW3?

[JessicaMeixner-NOAA]

Yes, I do mean 9 degrees :)

Yes, for now I'm thinking 9 degree for both, but I can make a 5 degree, I just know I can't do it today and I don't want to make promises about when. I figure this way, we're at least getting the technical aspects of it in.

[DeniseWorthen]

OK, I'll also try to test w/ adding, but I'm also not sure about my own timeline.

[DeniseWorthen]

I'm moving this back into draft status while I work on adding the WAV component to the ultra-low configurations.

[DeniseWorthen]

@JessicaMeixner-NOAA Referring to this comment, you created a 9deg structured and unstructured configuration. But I also see in there ww3_grid.inp.glo_5deg. Can use that for the 5deg WAV configuration? It seems the only the only config we'd be lacking at this point would be 5deg unstructured.

[DeniseWorthen]

Nevermind---just checked and only the unstructured grid is desired for the ultra low configurations.
