polaris.tasks.mesh.spherical.unified.sizing_field.BuildSizingFieldStep

class polaris.tasks.mesh.spherical.unified.sizing_field.BuildSizingFieldStep(component, coastline_step, river_step, subdir)

Build a unified sizing field on a shared lat-lon target grid.

The step reads the prepared coastline and river-network products for one mesh, delegates ocean-background construction to the mesh family, and writes a multi-variable sizing-field dataset to sizing_field.nc.

Variables:

• coastline_step (polaris.Step) – The shared coastline-preparation step whose outputs are consumed

• river_step (polaris.Step) – The shared lat-lon river-network step whose masks are consumed

• sizing_field_filename (str) – Name of the output sizing-field NetCDF file

__init__(component, coastline_step, river_step, subdir)

Create a new step.

Parameters:

• component (polaris.Component) – The component the step belongs to

• coastline_step (polaris.Step) – The shared coastline-preparation step for the lat-lon grid

• river_step (polaris.Step) – The shared lat-lon river-network step

• subdir (str) – The subdirectory within the component work directory where the step runs

Methods

__init__(component, coastline_step, ...)	Create a new step.
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 that must be produced by this step and may be made available as an input to steps, perhaps in other tasks.
check_properties()	This method should be overridden to check properties of step outputs
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()	Build the sizing-field dataset and write it to NetCDF.
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()	Link coastline and river products, configure the mesh family, and declare outputs.
validate_baselines()	Compare variables between output files in this step and in the same step from a baseline run if one was provided.
