The current release of CESM1.0 contains 5 component sets for building WACCM4.

Of these, 3 are B-compsets, with all fully active atmosphere (WACCM), land (CLM), ocean (POP), sea ice (CICE); and stub land ice (SGLC). These should be run at f19_g16 resolution, which puts the ocean model on its own grid:

B_1850_WACCM (short name B1850W): Pre-industrial (perpetual year 1850AD)

B_1850_WACCM_CN (B1850WCN): Pre-industrial with carbon-nitrogen cycle in CLM. Scientifically validated at 1.9x2.5_gx1v6.

B_1850-2000_WACCM_CN (B20TRWCN): 20th Century (1850-2000 transient) with carbon-nitrogen cycle in CLM. Scientifically validated at 1.9x2.5_gx1v6.

The remaining 2 are F-compsets, with fully active atmosphere (WACCM), land (CLM); prescribed sea ice (CICE); data ocean (SST data mode); and stub land ice (SGLC). These should be run at f19_f19 or f45_f45 resolution:

F_1850_WACCM (F1850W): Pre-industrial (perpetual year 1850AD)

F_2000_WACCM (FW): Present-day (perpetual year 2000AD)

You could try it on your own, however, NCAR does not support running WACCM at 0.95°x1.25° horizontal resolution at this time. This will be supported with the release of CESM2.0.

Thanks very much for your reply.I have tried to run WACCM at 0.95°x1.25° horizontal resolution. It shows some problem. According to your reply, I think cesm1.2.2 version may not support this. Do you know what time CESM 2.0 is available? Best wishes,Jiarong
