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
