oggm.core.massbalance.PastMassBalance

class oggm.core.massbalance.PastMassBalance(gdir, mu_star=None, bias=None, prcp_fac=None, filename='climate_monthly', input_filesuffix='')

Mass balance during the climate data period.

__init__(gdir, mu_star=None, bias=None, prcp_fac=None, filename='climate_monthly', input_filesuffix='')

Initialize.

Parameters:

gdir : GlacierDirectory

the glacier directory

mu_star : float, optional

set to the alternative value of mustar you want to use (the default is to use the calibrated value)

bias : float, optional

set to the alternative value of the calibration bias [mm we yr-1] you want to use (the default is to use the calibrated value) Note that this bias is substracted from the computed MB. Indeed: BIAS = MODEL_MB - REFERENCE_MB.

prcp_fac : float, optional

set to the alternative value of the precipitation factor you want to use (the default is to use the calibrated value)

filename : str, optional

set to a different BASENAME if you want to use alternative climate data.

input_filesuffix : str

the file suffix of the input climate file

Methods

__init__(gdir[, mu_star, bias, prcp_fac, …])	Initialize.
get_annual_mb(heights[, year])	Like self.get_monthly_mb(), but for annual MB.
get_ela([year])	Compute the equilibrium line altitude for this year
get_monthly_climate(heights[, year])	Monthly climate information at given heights.
get_monthly_mb(heights[, year])	Monthly mass-balance at given altitude(s) for a moment in time.
get_specific_mb(heights, widths[, year])	Specific mb for this year and a specific glacier geometry.
