Description:

#3203

In order for more general users to use ufs-weather-model, we want to make ufs-weather-model being able to compile on native AWS (as a new computing platform, or machine). This is a part of making Global-Workflow porting to native AWS.

#3214

Remove hard coded base line date associated with Parallelworks (NOAACloud) regression test CI script

#3219

Adding new and updating old FAQs

#3228

Update the LM4-driver hash to work with FMS 2025.03. This hash is required for the upgrade to spack-stack v2.1.0 and has also been tested with those compilers via PR #3174 .
Update rt.conf to run lm4 tests on Ursa & Orion (rather than Hera & Orion).

Acorn logs are there as well, now.

Acorn logs are there as well, now.

I also moved them to /scratch4/NCEPDEV/stmp/Brian.Curtis which might be more accessible.
