Quick howto use
To install:
pip install mom-utils
Some uses:
-
The input.nml do not require any order, so it is usually not fun to compare two different input.nml. This command is different then a regular diff, since it doesn't care about the order of the variables. The output show what is different, or what is defined in only one of the files.
mom_namelist compare input.nml input2.nml
-
Inside python, one can read an input.nml setup, change one parameter, and write into another input2.nml like this:
nml_text = open('input.nml', 'r').read()
cfg = mom_utils.nml_decode(nml_text)
cfg['ocean_model_nml']['dt_ocean'] = 7200
output = open('input2.nml', 'w')
output.write(mom_utils.yaml2nml(cfg))
-
Some namelists/parameters changed or disapear between MOM4 and MOM5. The task "check" evaluates if all namelists/parameters in the input.nml are declared in the code.
mom_namelist check --momsrc=mom/src myexperiments/exp1/input.nml
-
Task 4to5 converts a namelist for MOM4 to a namelist for MOM5
mom_namelist 4to5 input.nml > ./input.nml.new
