oggm.core.massbalance.LinearMassBalance#

class oggm.core.massbalance.LinearMassBalance(ela_h, grad=3.0, max_mb=None)[source]#

Constant mass balance as a linear function of altitude.

Attributes
ela_h: float

the equilibrium line altitude (units: [m])

grad: float

the mass balance gradient (unit: [mm w.e. yr-1 m-1])

max_mb: float

Cap the mass balance to a certain value (unit: [mm w.e. yr-1])

temp_bias

Change the ELA following a simple rule: + 1K -> ELA + 150 m

__init__(ela_h, grad=3.0, max_mb=None)[source]#

Initialize.

Parameters
ela_h: float

Equilibrium line altitude (units: [m])

grad: float

Mass balance gradient (unit: [mm w.e. yr-1 m-1])

max_mb: float

Cap the mass balance to a certain value (unit: [mm w.e. yr-1])

Methods

__init__(ela_h[, grad, max_mb])

Initialize.

get_annual_mb(heights, **kwargs)

Like self.get_monthly_mb(), but for annual MB.

get_ela([year])

Compute the equilibrium line altitude for a given year.

get_monthly_mb(heights, **kwargs)

Monthly mass balance at given altitude(s) for a moment in time.

get_specific_mb([heights, widths, fls, year])

Specific mb for this year and a specific glacier geometry.

Attributes

temp_bias

Change the ELA following a simple rule: + 1K -> ELA + 150 m
