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.
Parameters: - 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’].
