oggm.core.massbalance.LinearMassBalance

class oggm.core.massbalance.LinearMassBalance(ela_h, grad=3.0, max_mb=None)

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)

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_annual_specific_mass_balance(fls, year)	Get annual specific mass balance from multiple flowlines.
get_ela([year])	Get 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 mass balance for a given glacier geometry.
is_year_valid(year)	Checks if a given date year be simulated by this model.
reset_state()	Reset any internal state of the model.

Attributes

temp_bias

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