In CLM4.0 irrigation and crop can NOT be used together see bug number 1326 in the
models/lnd/clm/doc/KnownBugs file. However, in contrast CLM4.5 irrigation can ONLY be used WITH crop.
To turn on irrigation for either CLM4.0 or CLM4.5 we simply add "-irrig on" to CLM_BLDNML_OPTS
. Just as in the crop example we
also change RUN_TYPE
to startup so that we don't use
an initial condition file that is incompatible with irrigation.
Example 4-2. Example Irrigation Simulation
> cd scripts # Note here we do a CLMSP simulation as that is what has been validated > ./create_newcase -case IRRIG -res f19_g16 -compset I -mach yellowstone_intel > cd IRRIG # Append "-irrig" to |
Caution |
For CLM4.0 we have only run the irrigation model with CLM4.0-SP (i.e. without the CN model). We recommend that if you want to run the irrigation model with CLM4.0-CN, that you do a spinup as outlined in the examples below. But, more than that you may need to make the adjustments we discuss in the Section called Build-Namelist options that should NOT be exercised: in What is scientifically validated and functional in CLM4.5 in CESM1.2.0?. |
