compass.landice.tests.ismip7_calibration.ais.remap_masks.RemapMasks

class compass.landice.tests.ismip7_calibration.ais.remap_masks.RemapMasks(test_case)

A step that remaps the ISMIP7 masks onto the MALI mesh.

The calibration aggregates modelled melt over IMBIE2 drainage basins (J1, J3), over bins of equal buttressing importance (J2), and over the Pine Island and Dotson ice shelves (J4). Those masks are distributed on the ISMIP polar stereographic grid; this step puts them on the MALI mesh so that the aggregation happens in MALI’s own discretization.

Remapping is nearest neighbour throughout, since every field is categorical.

Two basin-numbering conventions are in play and they differ by one. ISMIP7’s basin_numbers_ismip8km_v2.nc is 0-based, 0-15, with basin 9 the Eastern Amundsen and basin 14 Ronne-Filchner, which is how the protocol refers to them. MALI’s ismip6shelfMelt_basin is 1-based, 1-16. Both are written here, under distinct names, so that neither can be silently reinterpreted as the other – a mistake that produces plausible-looking but wrong basin aggregates rather than an error.

__init__(test_case)

Create the step

Parameters:

test_case (compass.landice.tests.ismip7_calibration.ais.Ais) – The test case this step belongs to

Methods

__init__(test_case)	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 this step of the test case
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.
