use multi-year daily SST in CCSM4_amip run

[yjin7@masonlive_gmu_edu]

Hello,

I plan to run CCSM4 with F_2000_CN compset, but I need to use my own SST file. It is daily SST and it spans from the year 2125-2154, with the resolution 1.9x2.5 degree. I will run the model for 30 days, which means for each day the atmosphere responds to a different SST. But I am not sure how to modify the model. Here is what I have in my mind:
-------------------------------------------------------------
1. To prepare for the SST data, I need to firstly interpolate my own SST file to the grid of the file: hurrell_sst_ifrac.1x1.050606.nc, and change the time and sea ice (daily sea ice data) also. Then keep all the other variables unchanged.

2. In env_conf.xml, I need to change DOCN_SSTDATA_FILENAM to my own SST file name, and change DOCN_SSTDATA_YEAR_START and DOCN_SSTDATA_YEAR_END.

3. in ./Buildconf/docn.buildnml.csh, I need to change the following lines to point to my own SST file
set dat_dompath = $DIN_LOC_ROOT/ocn/docn7/SSTDATA
set dat_domfile = hurrell_sst_ifrac.1x1.050606.nc
set dat_datpath = $DIN_LOC_ROOT/ocn/docn7/SSTDATA
set dat_datfile = hurrell_sst_ifrac.1x1.050606.nc

Also change these lines.
set DOMAINFILE = ${mod_dompath}/${mod_domfile}
set DATAMODE = SSTDATA
set year_align = 1
set year_start = 1
set year_end = 1
set STREAM = HURRELL
set STREAM1TXT = docn.stream.txt

4. in docn.input_data_list change the file to my own SST file.
-------------------------------------------------------------
But I wonder
1) in env_conf.xml file, if it is correct to change the value of DOCN_SSTDATA_YEAR_START to 2125 and DOCN_SSTDATA_YEAR_END to 2154?
2) in docn_buildnml.csh, do I need to change the DATAMODE? how can I change the values for year_align, year_start and year_end, plus the STREAM and STREAM1TXT?

I'd really appreciate any suggestions. Thanks.
