oggm_edu.SurgingGlacier#

class oggm_edu.SurgingGlacier(bed=None, mass_balance=None)#

A surging glacier. This will have the same attributes as a normal glacier but with some extensions e.g. normal years and surging years.

__init__(bed=None, mass_balance=None)#

Initialise the surging glacier. Inherit attributes and methods from the Glacier class and extend it with some attributes specific for surging glaciers.

Methods

__init__([bed, mass_balance])

Initialise the surging glacier.

add_random_climate(duration, temperature_range)

Append a random climate to the future mass balance of the glacier.

add_temperature_bias(bias, duration[, noise])

Add a gradual temperature bias to the future mass balance of the glacier.

copy()

Return a copy of the glacier.

plot()

Plot the current state of the glacier.

plot_history()

Plot the history of the surging glacier.

plot_mass_balance()

Plot the mass balance profile of the glacier.

plot_state_history([interval, eq_states])

Plot the state history of the glacier (thicknesses) at specified intervals.

progress_to_equilibrium()

Surging glaciers do not really have an eq.

progress_to_year(year)

Progress the surging glacier to specified year.

reset()

Reset the state of the surging glacier.

summary()

A summary of the glacier, in the form of a pandas dataframe.

Attributes

accumulation_area_ratio

The accumulation area ratio.

age

Set the age of the glacier.

annual_mass_balance

The annual mass balance at each grid point of the glacier.

basal_sliding

Set the sliding parameter of the glacier

basal_sliding_surge

creep

Set the value for the creep parameter A in Glens equation.

current_state

For advanced users: get access to the current OGGM Flowline object.

ela

Expose the mass balance ela for the glacier.

eq_states

Glacier equilibrium states.

history

The history of the glacier.

mass_balance

Glacier mass balance.

mb_gradient

Expose the mass balance gradient.

normal_years

Number of years that the glacier progress without surging.

response_time

The response time of the glacier.

specific_mass_balance

The specific mass balance of the glacier [m w.e.

state_history

The state history of the glacier, i.e. geometrical changes over time.

surging_years

Number of years that the glacier progress during surges.
