How can I control which datm.streams.txt.* files are generated?

[JuliaZhang]

What version of the code are you using?
CESM2.1.3

Have you made any changes to files in the source tree?
No.

Describe every step you took leading up to the problem:
I created two cases using different compsets respectively.
After executing ./preview_namelists , the corresponding streams files were generated in the CaseDocs folder.

Describe your problem or question:
My question is that why are the streams files of these two cases different? What determines the datm.streams.txt.* files?

For the case created with COMPSET: 2000_DATM%1PT_CLM50%SP_SICE_SOCN_MOSART_SGLC_SWAV, the streams files are these three.


For the case created with COMPSET: 2000_DATM%GSWP3v1_CLM50%BGC-CROP_SICE_SOCN_MOSART_CISM2%NOEVOLVE_SWAV, the streams files are these five.

You've basically answered this yourself. The different options to DATM and CLM in the compset name determine what streams you are using for DATM. You can create a custom compset yourself say you wanted to add a different DATM stream. It sounds like you are trying to set up a CLM standalone case, so I will move this to the CLM forum.

Along the lines of @dbailey's response, you may be able to create a custom compset, such as
2000_DATM%GSWP3v1_CLM50%SP_SICE_SOCN_MOSART_SGLC_SWAV
to get the datm streams from the second case into your first one. Alternatively, you could try modifying the generated namelist files in the case, so that they point to whatever stream files you like.
