@uturuncoglu I'm having an issue w/ the land configurations, but not directly related to this PR.

I'm working on ufs-community/ufs-weather-model/issues/1800 but I'm getting unallocated arrays for the sbs land component. I think this is because the instantaneous coupling fields I want to use (instead of the mean fields) are outside of a cpllnd flag in GFS_typedefs.F90. So, for example,

https://github.com/NOAA-EMC/fv3atm/blob/a13a239a746cb95c74bbe5841f300cb75f8b80d9/ccpp/data/GFS_typedefs.F90#L2869-L2871

The fields I need instead are, for example, dlwsfci_cpl and dswsfci_cpl. As I've noted in the ufs issue, the mean and inst fields available in FV3atm are not b4b, but generally differ by ~O-12 or less.

I think what I needs is for all the inst fields which are currently under the only the cplflx flag but which are used by the lnd sbs need to be moved to the the cplfx=.true. or cpllnd=.true. block. Does this seem right?

Also, I noted that all the net SW bands are being allocated when cplfx=.true. or cpllnd=.true.. These don't seem to be used in either of those two configurations. Are they really required?

[uturuncoglu]

@DeniseWorthen I agree with you. If there is a filed that needs to be used by land then you could move them under cplfx=.true. or cpllnd=.true. statment. I think this will not affect anything in terms of land coupling. The shortwave bands are not used by the land component. We are just getting net or downward (then calculating net internally) based on the configuration. Let me know if you need help about testing.

[DeniseWorthen]

@uturuncoglu Thanks. These are the banded sw fields currently in the cpllnd/cplflx block

      allocate (Coupling%nnirbmi_cpl (IM))
      allocate (Coupling%nnirdfi_cpl (IM))
      allocate (Coupling%nvisbmi_cpl (IM))
      allocate (Coupling%nvisdfi_cpl (IM))
      allocate (Coupling%nnirbm_cpl  (IM))
      allocate (Coupling%nnirdf_cpl  (IM))
      allocate (Coupling%nvisbm_cpl  (IM))
      allocate (Coupling%nvisdf_cpl  (IM))

None of those are actually used by LND (either SBS or component)?

[uturuncoglu]

@DeniseWorthen I am sure they are not used by the land component but maybe FV3 needs them. Maybe I got error in the initial implementation and decided to put it under also land. It is hard to memorize. If you remove them and land sbs runs, then there is no any issue.

[uturuncoglu]

@DeniseWorthen BTW, if you look at CMEPs wiring for land component, there is no any field like sw bands.

[DeniseWorthen]

@uturuncoglu Thanks. I suspect they need to be under cplflx, but I agree I don't see any reason for them to be in the cpllnd block.

I know from the CMEPS side that the banded sw down components are used, but the ones in that block are the net sw bands. I will do some testing.

edit: banded down is used only for the DATM configuration

Please, go ahead to merge this pr. All tests were done at weather model side.
