polaris.tasks.ocean.realistic_global.init.remap_woa23.RemapWoa23Step

class polaris.tasks.ocean.realistic_global.init.remap_woa23.RemapWoa23Step(component, subdir, extrapolate_step, woa23_map_step)

A step for applying the WOA23 mapping weights built by Woa23MapStep, remapping the extrapolated WOA23 hydrography product from the native 0.25-degree latitude-longitude grid to MPAS cell centers.

This step is serial: the MPI work of building the mapping file happens in Woa23MapStep, and ncremap runs in serial here.

Variables:

• extrapolate_step (polaris.Step) – The upstream step that produces the extrapolated WOA23 product.

• woa23_map_step (polaris.Step) – The upstream step that builds the WOA23-to-mesh mapping file.

__init__(component, subdir, extrapolate_step, woa23_map_step)

Create the step.

Parameters:

• component (polaris.tasks.ocean.Ocean) – The ocean component the step belongs to.

• subdir (str) – The subdirectory for the step.

• extrapolate_step (polaris.Step) – The step that produces woa23_decav_0.25_jan_extrap.nc.

• woa23_map_step (polaris.Step) – The step that builds the WOA23-to-mesh mapping file.

Methods

__init__(component, subdir, ...)	Create the step.
add_cf_check([filename])	Check an output file for CF compliance after the step runs.
add_dependency(step[, name])	Add step as a dependency of this step (i.e. this step can't run until the dependency has finished).
add_input_file([filename, target, database, ...])	Add an input file to the step (but not necessarily to the MPAS model).
add_output_file(filename[, validate_vars, ...])	Add the output file to the step
add_property_check(filename, check_properties)	Add a single conservation comparison for an output file
check_cf()	Check the files added with add_cf_check() for CF compliance.
check_properties()	Check conservation properties of the output files of this step.
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 polaris.Step.add_input_file() and polaris.Step.add_output_file().
run()	Remap WOA23 CT and SA from the 0.25-degree lat-lon source grid to MPAS cell centers, writing woa23_on_mesh.nc.
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.
set_shared_config(config[, link])	Replace the step's config parser with the shared config parser
setup()	Declare the WOA23 input file.
validate_baselines()	Compare variables between output files in this step and in the same step from a baseline run if one was provided.
work_path(*filenames)	Get the absolute path to a file or directory in the step's work directory

Attributes

cores	the number of cores this step needs, in total
gpus	the number of GPUs this step needs, in total
may_span_nodes	whether this step's cores and GPUs may come from several nodes
min_cores	the number of cores this step needs in order to run at all
min_gpus	the number of GPUs this step requires, in total
