@EdwardSnyder-NOAA do you think we need to update https://github.com/EdwardSnyder-NOAA/land-DA_workflow/blob/ss160-container-update/sorc/test/ci/Dockerfile ?

[EdwardSnyder-NOAA]

Yes, @jkbk2004 I'll need to update that file. I got it to work but had to make a number of changes that I think could be resolved in a more elegant way. I'll try to get those changes in today.

Just a reminder this PR is for the previous ufs model hash. I'm still working on building the spack-stack with the proper modules to support the new ufs model hash.
