ERROR: ROF_GRID is null MOSART_MODE not NULL

Dear scientists of NCAR

I cut a regional surfcase dataset and domain dataset from the default 0.125x0.125 spatial resolution surfdata and domain dataset without changing the resolution by using the CLM5 tools.

Using the regional surfdata and domain data, I tried to create a case to simulate the streamflow. The case was set up with compset of "I2000Clm50SpGs", which means that the river routing moduel is "MOSART".

The setup information is as below:

./xmlchange NTASKS=80
./xmlchange DATM_CLMNCEP_YR_ALIGN=1980
./xmlchange DATM_CLMNCEP_YR_START=1980
./xmlchange DATM_CLMNCEP_YR_END=1980
./xmlchange DIN_LOC_ROOT=/home/dayon/inputdata
./xmlchange DIN_LOC_ROOT_CLMFORC=/home/dayon/inputdata/lmwg
./xmlchange RUN_STARTDATE=1980-01-01
./xmlchange STOP_N=1
./xmlchange STOP_OPTION=nyears
./xmlchange CLM_FORCE_COLDSTART='on'
./xmlchange REST_N=1
./xmlchange REST_OPTION=nyears
./xmlchange ATM_DOMAIN_FILE=domain.lnd.0.125x0.125_longtan_c210618.nc
./xmlchange LND_DOMAIN_FILE=domain.lnd.0.125x0.125_longtan_c210618.nc
./xmlchange MOSART_MODE=ACTIVE

However, when building the case, the shows that
ERROR: ROF_GRID is null MOSART_MODE not NULL

How to set the ROF_GRID? and how to add the lnd2rof_fmapname?

Do you really want to have MOSART active for you case? You can, but you'll need to do a bunch of work to get it setup. If you aren't going to really look at MOSART you might as well turn it off. Also depending on what your regional grid looks like, it might not make a lot of sense to run MOSART over a limited area where the rivers don't flow through the entire grid. You'll have a lot of rivers that end in stubs or go outside the domain, so analysis on them is pretty limited.

So to turn MOSART off with your setup...

./xmlchange MOSART_MODE=NULL

Thanks, Erik. I do want to look at the results simulated by MOSART, even though in a small region. What I need to do to get it setup?

How to handle river and ocean in the regional offline simulations with CLM5?

Dear Community, I had a problem when I intend to run the regional case within the CLM5. If the simualtion domain comprises the coastal regions or regions along the river, I was wondering that how to calculate the averaged fluxes on these grid cells. Did it call the Ocean module (POP) or the...

I am trying to run with my own regional 0.5*0.5 degree resolution based on the I1850CLM45CN compset, set RTM_MODE=ACTIVE. I used the "ncks" command to clip the global rdirc file to the area I am run trying to run on Many errors occurred when the model is actually run... So I want to know...
