docn files, domain file consistent with CESM PIcontrol?

[aswann2]

For context: my overall goal is to spinup the land carbon cycle in equilibrium with a modified atmosphere and then connect it back to an emissions-driven b-case.

Right now I'm trying to make an 1850 F-case (data ocean, active atmosphere) run that uses SST and sea ice from the coupled model PIcontrol so I can save coupler output to then run an I-case (data atm, active land) to spin up land carbon.

My Buildconf/docn.input_data_list looks like this:

domain1 = /glade/campaign/cesm/cesmdata/inputdata/ocn/docn7/domain.ocn.1x1.111007.nc
file1 = /glade/campaign/cesm/cesmdata/inputdata/atm/cam/sst/sstice_b.e21.B1850.f09_g17.CMIP6-piControl.001_0.9x1.25_yrs500-519_climo_c20190403.nc
domainfile = /glade/campaign/cesm/cesmdata/inputdata/share/domains/domain.ocn.gx1v7.151008.nc

But I don't think these domain files are compatible with the SSTICE file I selected. I'm not sure how to select the correct files, or if I need to make my own?
I get this error in my ocn log file:

(shr_dmodel_readstrm) open   : /glade/campaign/cesm/cesmdata/inputdata/atm/cam/sst/sstice_b.e21.B1850.f09_g17.CMIP6-piControl.001_0.9x1.25_yrs500-519_climo_c20190403.nc

ERROR: (shr_dmodel_readstrm) ERROR in data sizes

Can anyone point me to a combination of SSTICE and domain files that match and allow me to use coupled model SST and sea ice as my docn rather than observed? Or do I have to create these files? If so how do I create them from a preindustrial control B-case? I need my climate in the f-case to be in equilibrium with the B-case.

Here is my case directory:
/glade/u/home/aswann/cesmruns/cases/f.e21.F1850.f09_g17.FLAT10ctrl-esm.001.leafcn_high.bgc_spinup

And my run directory:
/glade/derecho/scratch/aswann/f.e21.F1850.f09_g17.FLAT10ctrl-esm.001.leafcn_high.bgc_spinup/run

compset: 1850_CAM60_CLM50%BGC-CROP_CICE%PRES_DOCN%DOM_MOSART_SGLC_SWAV
(should I be using a different CICE?)

all of the run setup information is in this script:
/glade/u/home/aswann/cesmruns/makeRunScripts/run_script_f.e21.F1850.f09_g17.FLAT10ctrl-esm.001.leafcn_high.bgc_spinup.sh

Thanks to CC Bitz for this answer!

I had compiled the model on grid f09_g17 because that was the resolution of the PI control run that I was branching from. But the SST and ICE file made from that same control run had be re-gridded to the atmosphere grid 0.9x1.25.

I created a new case with the f09_f09_mg17 grid resolution and was able to use that SST and ICE file successfully.

The other option would be to recreate a new SST and ICE file from the CESM PI control without re-gridding (keeping f09_g17).
