new atmos res C1120

[biljanaorescanin]

I am not sure do we need to add C1120 to gcm_setup?
It is candidate for FP but I am not sure what is good time and do we need to add it as option.
There are matching PRs for boundary conditions and remap restarts packages but those we did since we do use them.
GEOS-ESM/GEOS_Util#94
GEOS-ESM/GEOSgcm_GridComp#961

Also if this starts running as candidate it will always have v12 bcs as default and I think 181 lev.

What do you think @mathomp4 and @sshakoor1 ?

I think we are good here. The c1120 resolution is in the candidate v12 branch added by @wmputman:

GEOSgcm_App/gcm_setup

Line 245 in 2b1739f

echo " ${C2}c1120 - 1/12 deg (${C1} 8.0 km${C2}) ${CN}"

I mean, it doesn't work and won't until the bcs are in the "right" place, but it's there!

What do you mean by bcs are not at right place?
Both Bill and I use it from centralized location:

@biljanaorescanin Oh. I guess I didn't know that the c1120 were there yet! I guess I thought Bill or others were pointing to a "temporary" spot. 😄
