"ice_ic" when replacing SST and sea_ice

[liren]

Dear all,

I am trying to run a "F2000climo" compset using CESM2.1.3 and I want to replace the climatology SST and sea-ice with other data. Also I want to force the atmospheric component with SST & sea-ice in different year.

Now, I have successfully modified the input data. I have changed the user_docn.streams.txt.prescribed file like this:

<fieldInfo>
   <variableNames>
     SST_cpl t
   </variableNames>
   <filePath>
     /home/sst
   </filePath>
   <fileNames>
    SST.nc
   </fileNames>
   <offset>
      0
   </offset>
</fieldInfo>
</file>

Also, in order to change the sea-ice field, I use

./xmlchange SSTICE_DATA_FILENAME="sea-ice.nc"

And CESM can run normally. But:
1. I wonder if this is the right way to replace sea ice and SST
2. I had just found that the variable "ice_ic" in file ”./CaseDocs/ice_in“ is

ice_ic = "f.e20.FHIST.f09_f09.cesm2_1.001_v2.cice.r.2000-01-01-00000.nc"

because I want to restart manually base on the restart file. I wonder if this variable (ice_ic) should be modified.

Sincerely,
Liren

For an F compset, you have a combined SST/ICEFRAC file so that CICE and DOCN are reading in the same dataset. The SST and ICEFRAC need to be consistent. Have a look at the SSTICE variables in env_run.xml. This is where you would make changes. Also, I am moving this to the CAM forum.

Thanks for your reply! I have checked "env_run.xml" and xml file seems right.
