@MatthewPyle-NOAA Should we start testing this pr?

[MatthewPyle-NOAA]

@jkbk2004 Yes, but wondering if we could combine it with #2249 to resolve both production/RRFS.v1 PRs. But happy to keep them separate if that is easier.

It might be easier to go separately. I will start testing this pr on hera/hercules.

@MatthewPyle-NOAA we can start merging sub-component PRs.

Thanks @jkbk2004 - remind me, start with atmos_cubed_sphere and work up?
