oggm.tasks.fixed_geometry_mass_balance(gdir, settings_filesuffix='', ys=None, ye=None, years=None, monthly_step=False, use_inversion_flowlines=True, climate_filename='climate_historical', climate_input_filesuffix='', temperature_bias=None, precipitation_factor=None, mb_model_class=None)

Computes the mass balance with climate input from e.g. CRU or a GCM.

Parameters:

gdirGlacierDirectory

The glacier directory to process.

settings_filesuffixstr, optional

You can use a different set of settings by providing a filesuffix. This is useful for sensitivity experiments. Code-wise the settings_filesuffix is set in the @entity-task decorator.

ysint, optional

Start year of the model run (default: from the climate file). date)

yeint, optional

End year of the model run (default: from the climate file).

yearsarray_like[int], optional

Override ys and ye with the years of your choice.

monthly_stepbool, default False

Store the diagnostic data at a monthly time resolution. If False, stores it at an annual resolution.

use_inversion_flowlinesbool, default True

Use the inversion flowlines instead of the model flowlines.

climate_filenamestr, default ‘climate_historical’

Name of the climate file, e.g. ‘climate_historical’, ‘gcm_data’.

climate_input_filesuffix: str, optional

Filesuffix for the input climate file.

temperature_biasfloat, optional

Add a bias to the temperature timeseries.

precipitation_factor: float, optional

Multiplicative factor applied to the precipitation time series. If None, uses the precipitation factor from the calibration in gdir.settings['prcp_fac'].

mb_model_classMassBalanceModel, defaults to MonthlyTIModel

The MassBalanceModel class to use.
