class mpas_analysis.shared.regions.compute_region_masks_subtask.ComputeRegionMasksSubtask(parentTask, regionGroup, meshName, subprocessCount=1, obsFileName=None, lonVar='lon', latVar='lat', useMpasMaskCreator=False)[source]

An analysis tasks for computing cell masks for regions defined by geojson features

Variables

  • regionGroup (str) – The name of one of the supported region groups (see mpas_analysis.shared.regions.get_region_info())

  • region (dict) – A dictionary of information about the region from mpas_analysis.shared.regions.get_region_info()

  • geojsonFileName (str) – A geojson file, typically from the MPAS geometric_features repository, defining the shapes to be masked

  • outFileSuffix (str) – The suffix for the resulting mask file

  • featureList (list of str) – A list of features to include or None for all features

  • maskFileName (str) – The name of the output mask file

  • obsFileName (str) – The name of an observations file to create masks for. But default, lon/lat are taken from an MPAS restart file

  • latVar (lonVar,) – The name of the longitude and latitude variables in obsFileName

  • meshName (str) – The name of the mesh or grid, used as part of the mask file name. Default is the MPAS mesh name

__init__(parentTask, regionGroup, meshName, subprocessCount=1, obsFileName=None, lonVar='lon', latVar='lat', useMpasMaskCreator=False)[source]

Construct the analysis task and adds it as a subtask of the parentTask.

Parameters

  • parentTask (AnalysisTask) – The parent task, used to get the taskName, config and componentName

  • regionGroup (str) – The name of one of the supported region groups (see mpas_analysis.shared.regions.get_region_info())

  • meshName (str) – The name of the mesh or grid, used as part of the mask file name. Default is the MPAS mesh name

subprocessCountint, optional

The number of processes that can be used to make the mask

obsFileNamestr, optional

The name of an observations file to create masks for. But default, lon/lat are taken from an MPAS restart file

lonVar, latVarstr, optional

The name of the longitude and latitude variables in obsFileName

useMpasMaskCreatorbool, optional

If True, the mask creator from mpas_tools will be used to create the mask. Otherwise, python code is used.

Methods

__init__(parentTask, regionGroup, meshName)

Construct the analysis task and adds it as a subtask of the parentTask.

add_subtask(subtask)

Add a subtask to this tasks.

check_analysis_enabled(analysisOptionName[, …])

Check to make sure a given analysis is turned on, issuing a warning or raising an exception if not.

check_generate()

Determines if this analysis should be generated, based on the generate config option and taskName, componentName and tags.

close()

Close the Process object.

expand_region_names(regionNames)

If regionNames contains 'all', make sure the geojson file exists and then return all the region names found in the file.

is_alive()

Return whether process is alive

join([timeout])

Wait until child process terminates

kill()

Terminate process; sends SIGKILL signal or uses TerminateProcess()

make_region_mask()

If the geojson mask file has not already been cached in the diagnostics or custom diagnostic directories, it will be created in the analysis output’s masks directory.

run([writeLogFile])

Sets up logging and then runs the analysis task.

run_after(task)

Only run this task after the given task has completed.

run_task()

Compute the requested climatologies

set_start_end_date(section)

Set the start and end dates in the config correspond to the start and end years in a given category of analysis

setup_and_check()

Perform steps to set up the analysis and check for errors in the setup.

start()

Start child process

terminate()

Terminate process; sends SIGTERM signal or uses TerminateProcess()

Attributes

BLOCKED

FAIL

READY

RUNNING

SUCCESS

UNSET

authkey

daemon

Return whether process is a daemon

exitcode

Return exit code of process or None if it has yet to stop

ident

Return identifier (PID) of process or None if it has yet to start

name

pid

Return identifier (PID) of process or None if it has yet to start

sentinel

Return a file descriptor (Unix) or handle (Windows) suitable for waiting for process termination.
