standalone atmosphere component

I am tring to run a standalone atmosphere component. I tried to create a caseby:create_newcase -case mycompset -res f19_f19 -user_compset 2000_CAM4%WCCM_XLND_XICE_XOCN_XROF_XGLC_XWAV -mach userdefinedThe error messages after the second cesm_setup are: infile is .../CESM/cesm1_2_0_bak/scripts/test/Buildconf/cplconf/cesm_namelist
ERROR: xocn is not a valid value for parameter ocn: valid values are docn,dom,socn,aquaplanet,pop2
ERROR: cam.buildnml.csh failed
ERROR: .../CESM/cesm1_2_0_bak/scripts/test/preview_namelists failed: 25344

The atmosphere needs some kind of data on it's lower boundary.    What you probably want is an F compset which has the longname
Code:
2000_CAM4_CLM40%SP_CICE%PRES_DOCN%DOM_RTM_SGLC_SWAV<br /><br />If you don't want an active land model either then you need to use aquaplanet FAQUAP

The FW (F_2000_WACCM) compset will give you a constant year 2000 with data ocean and sea ice components, and an active land component. We do not support the use of WACCM without an active land model.

If you are running with an active atmosphere, then you need to use cice%pres, which includes a thermodynamic calculation of surface temperature based on prescribed ice coverage and thickness. The data ice model (dice) couples only with the ocean, and will not calculate the surface temperatures needed by an active atmosphere.
