LGM inputs with cesm1.1

[s_albani@cornell_edu]

Hi!I am trying to set an LGM case with cesm1.1, starting from compset B_1850_CN -res f09_g16.The approach I took is trying to mimic /glade/p/cesm/cseg/runs/ccsm4_0/b40.lgm21ka.1deg.003/

With the .xml files and namelist modifications I've made the model builds, but the run crashes right away, the reason being related to "ldomain". The expected variable inputs seem different between cesm1.1 and the older version, as by the way is the case for "frivinp_rtm" and "fpftcon", as I noticed.The point where the model crashes is in the land, see lnd.log:Attempting to read ldomain from /glade/p/cesm/cseg/runs/ccsm4_0/b40.lgm21ka.1deg.003/SourceMods/src.clm//fracdata_0.9x1.25_lgm21ka.110315.nc(GETFIL): attempting to find local file fracdata_0.9x1.25_lgm21ka.110315.nc(GETFIL): using /glade/p/cesm/cseg/runs/ccsm4_0/b40.lgm21ka.1deg.003/SourceMods/src.clm//fracdata_0.9x1.25_lgm21ka.110315.nc This is done in .../lnd/clm/src/main/clm_initializeMod.F90The specific input was set as: ./xmlchange -file env_run.xml -id LND_DOMAIN_FILE -val fracdata_0.9x1.25_lgm21ka.110315.nc
If I ncdump fracdata_0.9x1.25_lgm21ka.110315.nc// global attributes:
        :Conventions = "NCAR-CSM" ;
        :History_Log = "created on: 03-15-11 10:34:40" ;
        :Logname = "nanr" ;
        :Host = "be1005en.ucar.edu" ;
        :fcamfile = "/fis/cgd/ccr/nanr/pmip3/lgm21ka/gen_domain/domain.lnd.fv0.9x1.25_gx1p21k.110315.nc" ;
        :fccsmdom = "" ;
        :fcamtopo = "" ;
        :fclmgrid = "" ;
        :fnavyoro = "" ;
        :frawtopo = "" ;
        :File_used = "/fis/cgd/ccr/nanr/pmip3/lgm21ka/gen_domain/domain.lnd.fv0.9x1.25_gx1p21k.110315.nc" ;
        :Source = "Community Land Model: CLM3" ;
        :Version = "$HeadURL: https://svn-ccsm-models.cgd.ucar.edu/clm2/trunk_tags/clm4_0_12/models/lnd/clm/tools/mkgriddata/creategridMod.F90 $" ;
        :Revision_Id = "$Id: creategridMod.F90 19052 2009-10-27 16:34:04Z erik $" ;

I am not sure how to deal with this, although I suspect interpinic is involved, but anyway I could not find the file “domain.lnd.fv0.9x1.25_gx1p21k.110315.nc”, which may be the one I am looking for? Thanks for the support!

As an addition to the post, I found that in the coupler mapping files namelists there is a different convention than older versions of the model. For most of the variables the association seems to be straightforward using /b40.lgm21ka.1deg.003/SourceMods/src.drv/*But there is also an additional variable I am not sure know how to deal with:lnd2roffmapname = /glade/p/cesm/cseg//inputdata/lnd/clm2/mappingdata/maps/0.9x1.25/map_0.9x1.25_nomask_to_0.5x0.5_nomask_aave_da_c120522.nc

Hi Samuel,Have you figured out this question? Does it matter if you keep the lnd2rof mapping file as the same with the default file? I met the similar problems in my LGM simulation with CESM1.2.2. In CESM1.2.2, the name and path of mapping files are modified in env_run.xml. As you said, some key mapping files can be read from /b40.lgm21ka.1deg.003/SourceMods/src.drv/, however, I am not sure whether it is OK to keep the following mapping files as the default. For example,ROF2LND_FMAPNAMEROF2LND_SMAPNAMELND2ROF_FMAPNAMEROF2OCN_FMAPNAMEDo you have any suggestions? Thanks!Wenwen
