@DeniseWorthen At this point I am not using inst_down_lw_flx and inst_down_sw_flx in NoahMP cap but using Faxa_swdn and Faxa_lwdn which are pointing mean values. Since, all the components under UFS Weather Model are switching to instantaneous fields, maybe NoahMP needs to switch those. Let me know what you think?

[uturuncoglu]

@DeniseWorthen Do you also plan to do changes in CMEPS/mediator/esmFldsExchange_nems_mod.F90? I think the other configurations under UFS Weather model are still using Faxa_lwdn which is the mean field if you check in fd_nems.yaml.

[DeniseWorthen]

@uturuncoglu Yes, there is a follow-on #1942 to this one which will switch the remaining field aliases to be inst. I've been making a series of PRs to get everything aligned, and I want the final PR to be only a change of alias, no code changes. Unfortunately I missed this cpllnd change that is needed in the #1925 that was just committed. That change was for the fields going TO atm.

[uturuncoglu]

@DeniseWorthen Okay. Thanks for the clarification. I think this PR good to go. In any case, I don't think but if I had issue in the land PR, I could fixed in there.

[DeniseWorthen]

@uturuncoglu I think it would be good to clean up the un-used fields in the cpllnd logical blocks. It isn't clear to me if you might end up using those in the future (the banded SW down for example) and so want to retain them, or if they really aren't required for the LND component after all.

[uturuncoglu]

@DeniseWorthen I could not see the place that land uses the banded SW down. Could you point me the code? Maybe this is already fixed in my PR but not sure. It would be nice to double check.

[DeniseWorthen]

@uturuncoglu I was looking at

https://github.com/NOAA-EMC/fv3atm/blob/a13a239a746cb95c74bbe5841f300cb75f8b80d9/ccpp/data/GFS_typedefs.F90#L2875-L2882

In your original commit to add the land component, these got moved from just a cpflx block into the cplflx or cpllnd block. These are actually the net SWs---I called them the down SWs by mistake.

[uturuncoglu]

@DeniseWorthen Okay. Those are not used by land and it is not required by NoahMP. In the sbs (and also fully coupled - in the outstanding PR) configuration FV3 is not coupled with ocean and only coupled by land (so, in this case cplflx = false but cpllnd = true) and maybe those parts are only required to satisfy some internal logic in the FV3 side since it was assuming that cplflx is always true if it is coupled. Does it makes sense?

[DeniseWorthen]

I'm a little confused, myself. Originally (prior to your first land PR), those fields were only in the cplflx block. But, they're actually not needed when coupling to ocean either (swnet is only needed by HAFS). I can try moving them back to the cplflx block and see if I can get a failure.

[DeniseWorthen]

This PR should not have been closed. This happens when you mistakenly 'sync' to develop on github and it discards the commits that are actually present in the PR.

I guess I can't re-open. I will need to re-create.
