compass.landice.tests.ismip7_calibration.ais.calibrate.Calibrate

class compass.landice.tests.ismip7_calibration.ais.calibrate.Calibrate(test_case, melt_forms)[source]

A step that runs the ISMIP7 parameter selection on the MALI ensemble.

The protocol draws random term weights and random targets within their uncertainties, and for each draw picks the parameter that minimises I = sum_i a_i J_i / median(J_i). The 5th, 50th and 95th percentiles of the resulting distribution are what the ISMIP7 projections need.

Because the objective normalises each term by its own median over the parameter ensemble, a minimised I is not comparable between melt forms – only between parameter values within one form. This step therefore reports a distribution per melt form and never a cross-form comparison of the objective.

Variables:

melt_forms (list of str) – The melt forms to calibrate

__init__(test_case, melt_forms)[source]

Create the step

Parameters:

Methods

__init__(test_case, melt_forms)

Create the step

add_input_file([filename, target, database, ...])

Add an input file to the step (but not necessarily to the MPAS model).

add_model_as_input()

make a link to the model executable and add it to the inputs

add_namelist_file(package, namelist[, ...])

Add a file with updates to namelist options to the step to be parsed when generating a complete namelist file if and when the step gets set up.

add_namelist_options(options[, out_name, mode])

Add the namelist replacements to be parsed when generating a namelist file if and when the step gets set up.

add_output_file(filename)

Add the output file that must be produced by this step and may be made available as an input to steps, perhaps in other test cases.

add_streams_file(package, streams[, ...])

Add a streams file to the step to be parsed when generating a complete streams file if and when the step gets set up.

constrain_resources(available_resources)

Constrain cpus_per_task and ntasks based on the number of cores available to this step

process_inputs_and_outputs()

Process the inputs to and outputs from a step added with compass.Step.add_input_file() and compass.Step.add_output_file().

run()

Run this step of the test case

runtime_setup()

Update attributes of the step at runtime before calling the run() method.

set_resources([cpus_per_task, ...])

Update the resources for the subtask.

setup()

Set up the test case in the work directory, including downloading any dependencies.

update_namelist_at_runtime(options[, out_name])

Update an existing namelist file with additional options.

update_namelist_pio([out_name])

Modify the namelist so the number of PIO tasks and the stride between them consistent with the number of nodes and cores (one PIO task per node).

update_streams_at_runtime(package, streams, ...)

Update the streams files during the run phase of this step using the given template and replacements.
