oggm.tasks.find_inversion_calving(gdir, water_level=None, fixed_water_depth=None, glen_a=None, fs=None, min_mu_star_frac=None)[source]

Optimized search for a calving flux compatible with the bed inversion.

See Recinos et al 2019 for details.

water_level : float

the water level. It should be zero m a.s.l, but: - sometimes the frontal elevation is unrealistically high (or low). - lake terminating glaciers - other uncertainties With this parameter, you can produce more realistic values. The default is to infer the water level from PARAMS[‘free_board_lake_terminating’] and PARAMS[‘free_board_marine_terminating’]

fixed_water_depth : float

fix the water depth to an observed value and let the free board vary instead.

glen_a : float, optional
fs : float, optional
min_mu_star_frac : float, optional

fraction of the original (non-calving) mu* you are ready to allow for. Defaults cfg.PARAMS[‘calving_min_mu_star_frac’].
