update-glm-config

name	update_glm_config
description	Safely updates specific calibration parameters in the glm3.nml file using f90nml, maintaining correct namelist group mapping and file integrity.

To update the configuration, use the f90nml library to parse the existing file. Map the parameters to their respective namelist groups: Kw to &light, coef_mix_hyp to &mixing, and wind_factor, lw_factor, and ch to &meteorology.

import f90nml

def update_glm_parameters(params):
    nml = f90nml.read('/root/glm3.nml')
    # Map parameters to their correct namelist groups
    nml['light']['Kw'] = params.get('Kw')
    nml['mixing']['coef_mix_hyp'] = params.get('coef_mix_hyp')
    nml['meteorology']['wind_factor'] = params.get('wind_factor')
    nml['meteorology']['lw_factor'] = params.get('lw_factor')
    nml['meteorology']['ch'] = params.get('ch')
