mpas_analysis.ocean.compute_anomaly_subtask.ComputeAnomalySubtask

class mpas_analysis.ocean.compute_anomaly_subtask.ComputeAnomalySubtask(parentTask, mpasTimeSeriesTask, outFileName, variableList, movingAveragePoints, subtaskName='computeAnomaly', alter_dataset=None)[source]

A subtask for computing anomalies of moving averages and writing them out.

Variables:

  • mpasTimeSeriesTask (MpasTimeSeriesTask) – The task that extracts the time series from MPAS monthly output

  • outFileName (str) – The file name (usually without full path) where the resulting data set should be written

  • variableList (list of str) – Variables to be included in the data set

  • movingAveragePoints (int) – The number of points (months) used in the moving average used to smooth the data set

  • alter_dataset (function) – A function that takes an xarray.Dataset and returns an xarray.Dataset for manipulating the data set (e.g. adding a new variable computed from others). This operation is performed before computing moving averages and anomalies, so that these operations are also performed on any new variables added to the data set.

__init__(parentTask, mpasTimeSeriesTask, outFileName, variableList, movingAveragePoints, subtaskName='computeAnomaly', alter_dataset=None)[source]

Construct the analysis task.

Parameters:

  • parentTask (AnalysisTask) – The parent task of which this is a subtask

  • mpasTimeSeriesTask (MpasTimeSeriesTask) – The task that extracts the time series from MPAS monthly output

  • outFileName (str) – The file name (usually without full path) where the resulting data set should be written

  • variableList (list of str) – Variables to be included in the data set

  • movingAveragePoints (int) – The number of points (months) used in the moving average used to smooth the data set

  • subtaskName (str, optional) – The name of the subtask

  • alter_dataset (function) – A function that takes an xarray.Dataset and returns an xarray.Dataset for manipulating the data set (e.g. adding a new variable computed from others). This operation is performed before computing moving averages and anomalies, so that these operations are also performed on any new variables added to the data set.

Methods

__init__(parentTask, mpasTimeSeriesTask, ...)

Construct the analysis task.

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.

get_mesh_filename()

Get the name of the MPAS mesh file for this component.

is_alive()

Return whether process is alive

join([timeout])

Wait until child process terminates

kill()

Terminate process; sends SIGKILL signal or uses TerminateProcess()

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()

Performs analysis of ocean heat content (OHC) from time-series output.

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()
