compass.landice.tests.ismip7_forcing.fracture.Fracture

class compass.landice.tests.ismip7_forcing.fracture.Fracture(test_group)

A test case for processing ISMIP7 fracture forcing data. Implements the surface-melt-driven ice shelf collapse pathways:

• Path A (process_excess_melt): excess meltwater after firn air content depletion.

• Path B (process_lake_properties): supraglacial lake mean depth and area fraction from Grau et al. (2025).

• Path C (process_shelf_collapse): the ice shelf collapse mask, in which a floating grid cell is flagged as collapsed when excess meltwater exceeds 72.5 mm/yr for 10 consecutive years.

__init__(test_group)

Create the test case

Parameters:

test_group (compass.landice.tests.ismip7_forcing.Ismip7Forcing) – The test group that this test case belongs to

Methods

__init__(test_group)	Create the test case
add_step(step[, run_by_default])	Add a step to the test case
check_validation()	Check the test case's "validation" dictionary to see if validation failed.
configure()	Configures test case
run()	This method is deprecated.
validate()	Test cases can override this method to perform validation of variables and timers
