@DeniseWorthen Do you think that we need to find more meaningful aliases for the new fields defined in the dictionary. We could try to come up a set of standard names for them but not sure. Let me know what you think?

[DeniseWorthen]

@uturuncoglu I'm not sure how useful the aliases are if we have the description. So, for example we could make an alias for Sw_ubry but it would basically be the description, something like alias: near_bottom_rms_wave_velocities_y? Do you know if SCHISM for example would prefer to import a field using a descriptive alias?

I do see now I should have probably named some of the new fields with "Fw" (as fluxes) and not "Sw" as states.

[uturuncoglu]

@DeniseWorthen Yes, SCHSIM follows convention like that. See following part, https://github.com/oceanmodeling/schism-esmf/blob/12e2ce43475fe85212c60de7894524d22a1bab96/src/schism/schism_nuopc_cap.F90#L414. It is not big deal and I am using short names at this point for the implementation but we might consider to add aliases and use them in the SCHSIM side. anyway, I'll let you know when PR is ready in ufs coastal side. So, you could check it.

[DeniseWorthen]

I see, thanks. We definitely might need aliases then.

@DeniseWorthen @JessicaMeixner-NOAA @janahaddad We had a meeting with costal team today. Here is our proposal,

• Let's keep this PR and also WW3 one active for now. So, it might be merged with the UFS WM around November time frame (waiting in freeze mode 2-3 months) once WW3 team have more resource. We have no rush at this point and we could still test the implementation in our end without any issue.

• In the mean time, I'll create a new branch in our UFS WM fork to bring all these changes. This will allow us to have further test in vortex coupling with a new configuration (we are working on it in Coastal side) and also create new RT to test it regularly. It will also help us to find issues in the coupling if we have and then we could fine tune the PR in here if it is required.

• Then, once top level UFS WM PR is merged, we could sync UFS Costal fork to get all the changes.

Anyway, let me know what do you think about this plan. We are open any other suggestion at this point.

[DeniseWorthen]

@uturuncoglu I do think it is a good idea for Coastal to test the changes in the WW3 cap as much as possible while we wait for the stoppage of PRs in WW3 to lift. Also keep in mind that once the stoppage lifts, PRs to dev/ufs-weather-model will most likely be further delayed as community development (going to the develop branch) will also need to proceed.

Also, I wanted to make Coastal aware of Issue NOAA-EMC/WW3#1298 in case you haven't seen it.

[uturuncoglu]

@DeniseWorthen That is great. BTW, Thanks for pointing the PIO PR.

[jiandewang]

@DeniseWorthen can you modify the PR tilte and add "update MOM6 to its main repo. 20250113 commit (20241127-PR)" ?

[DeniseWorthen]

@jiandewang I also added a commit message line for MOM6

[jiandewang]

@DeniseWorthen Thanks

[jkbk2004]

@BrianCurtis-NOAA do you want to go for merging this pr if we skip Acorn ?

[jkbk2004]

We can start merging process.

[jiandewang]

kust merged MOM6 with hash # 6fff095

Logs on Hercules weren't found for hrrr_control_2threads_gnu but test did pass. (More of an FYI / record keeping in case this keeps happening)

[jkbk2004]

Rocoto/Hercules is not that robust: a few cases are randomly dropped. But if jobs are resubmitted, all is ok.
