./case.build Create a mapping grid file

[tenghao]

Hello, everybody!


Create my own domain , surfdata, and land use timeseries for the research area according to the following process by clm5.0：

./mknoocnmap.pl -p $CENLAT,$CENLON -n $GRIDNAME -dy $DY -ny $NY -dx $DX -nx $NX

./mkmapdata.sh -r $GRIDNAME -f $GRIDFILE -t regional

./gen_domain -m $MAPFILE -o $OCNDOM -l $ATMDOM

./mksurfdata.pl -r usrspec -usr_gname $GRIDNAME -usr_gdate $CDATE -l $CSMDATA

./mksurfdata.pl -r usrspec -usr_gname $GRIDNAME -usr_gdate $CDATE -l $CSMDATA -y 1850-2000 -no_surfdata



Create newcase：

./create_newcase --case test_I2000Clm50BgcCrop --compset I2000Clm50BgcCrop --res CLM_USRDAT --machine myintel --compiler intel --run-unsupported

./case.setup

./case.build （ERROR: Need to provide valid mapping file between glc and lnd in xml variable glc2lnd_smapname ）



(1) After consulting the relevant information on the forum, I learned that it is necessary to create a corresponding mapping file through ./gen_cesm_maps. sh, but what confuses me is what input data is specified in ./gen_cesm_maps. sh(--fileatm --fileocn --filelnd --filertm)?



(2) Execute./mknoocmap.pl, and generate.

SCRIPgrid_SHJ1X1_nomask_c250228.nc

SCRIPgrid_SHJ1X1_noocean_c250228.nc

map_SHJ1X1_noocean_to_SHJ1X1_nomask_aave_da_250228.nc

Do these three nc data relate to the input data for./gen_cesm_maps.sh(--fileatm --fileocn --filelnd --filertm)? The --filelnd in./gen_cesm_maps.sh must be global. How should it be generated? In addition, if you want to execute. /gen_cesm_maps.sh, it seems that you need to modify create_ESMF_map.sh. How to modify create_ESMF_map.sh enough to make gen_cesm_maps.sh run?



(3) At the suggestion of others, I did not prepare the corresponding mapping file, but used the existing data to conduct the experiment.

/xmlchange GLC2LND_SMAPNAME=map_gland4km_TO_fv0.9x1.25_aave.161223.nc

/xmlchange GLC2LND_FMAPNAME=map_gland4km_TO_fv0.9x1.25_aave.161223.nc

/xmlchange LND2GLC_FMAPNAME=map_fv0.9x1.25_TO_gland4km_aave.161223.nc

/xmlchange LND2GLC_SMAPNAME=map_fv0.9x1.25_TO_gland4km_blin.161223.nc

While./case.build worked, I don't know if it will have any effect on the custom resolution study area？



Looking forward to the answer very much

With best wishes

Unfortunately I do not have insights into this, so my first suggestion is to try (3) in case it works.

Something else to mention is the mksurfdata_esmf tool, which has replaced the old mksurfdata_map tool, and is simpler to use. However, the new tool became available with the ctsm5.2 release, and may not be compatible with your version.
