oggm.core.massbalance.MultipleFlowlineMassBalance

class oggm.core.massbalance.MultipleFlowlineMassBalance(gdir, settings_filesuffix='', fls=None, mb_model_class=<class 'oggm.core.massbalance.MonthlyTIModel'>, use_inversion_flowlines=False, flowlines_filesuffix='', input_filesuffix=None, **kwargs)

Handle mass balance at the glacier level instead of flowline level.

Convenience class doing not much more than wrapping a list of mass balance models, one for each flowline.

This is useful for real-case studies, where each flowline might have different model parameters.

Attributes:

flslist

list of flowline objects

__init__(gdir, settings_filesuffix='', fls=None, mb_model_class=<class 'oggm.core.massbalance.MonthlyTIModel'>, use_inversion_flowlines=False, flowlines_filesuffix='', input_filesuffix=None, **kwargs)

Initialize.

Parameters:

gdirGlacierDirectory

the glacier directory

settings_filesuffixstr, optional

You can use a different set of settings by providing a filesuffix. This is useful for sensitivity experiments.

flslist, optional

list of flowline objects to use (defaults to ‘model_flowlines’)

mb_model_classMassBalanceModel, default MonthlyTIModel

the MassBalanceModel to use e.g. DailyTIModel, ConstantMassBalance.

use_inversion_flowlines: bool, optional

use ‘inversion_flowlines’ instead of ‘model_flowlines’

flowlines_filesuffixstr

suffix to the flowlines filename to use (could be ‘inversion_flowlines’ or ‘model_flowlines’, depending on ‘use_inversion_flowlines’). Default is ‘’

kwargskwargs to pass to mb_model_class
