oggm.core.massbalance.ConstantMassBalance

class oggm.core.massbalance.ConstantMassBalance(gdir, mu_star=None, bias=None, prcp_fac=None, y0=None, halfsize=15, filename='climate_monthly', input_filesuffix='')

Constant mass-balance during a chosen period.

This is useful for equilibrium experiments.

__init__(gdir, mu_star=None, bias=None, prcp_fac=None, y0=None, halfsize=15, 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 annual bias [mm we yr-1] you want to use (the default is to use the calibrated value)

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)

y0 : int, optional, default: tstar

the year at the center of the period of interest. The default is to use tstar as center.

halfsize : int, optional

the half-size of the time window (window size = 2 * halfsize + 1)

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_climate(heights[, year])	Average climate information at given heights.
get_ela([year])	Compute the equilibrium line altitude for this year
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.
