Multi_Tool (MTD): Feature Relative by Lead (with lead groupings)

model_applicaitons/medium_range/MTD_SeriesAnalysis_fcstGFS_obsGFS_FeatureRelative_SeriesByLead.conf

Scientific Objective

Demonstrate the capability in the Feature Relative use case but using output from the MET MODE Time Domain (MTD) tool.

Version Added

METplus version 4.1

Datasets

Forecast: NOAA Global Forecast System (GFS)

Observation: NOAA Global Forecast System (GFS) analysis

Climatology: None

Location: All of the input data required for this use case can be found in a sample data tarball. Each use case category will have one or more sample data tarballs. It is only necessary to download the tarball with the use case’s dataset and not the entire collection of sample data. Click here to access the METplus releases page and download sample data for the appropriate release: https://github.com/dtcenter/METplus/releases This tarball should be unpacked into the directory that you will set the value of INPUT_BASE. See Running METplus section for more information.

METplus Components

This use case first runs MODE Time Domain and ExtractTiles wrappers to generate tiles of data centered on objects defined using MTD. The MET regrid_data_plane tool is used to regrid the data (GRIB1 or GRIB2 into netCDF). Next, a series analysis by lead time is performed on the results and plots (.ps and .png) are generated for all variable-level-stat combinations from the requested variables, levels, and requested statistics. The final results are aggregated into forecast hour groupings as specified by the start and end increment in the METplus configuration file, as well as labels to identify each forecast hour grouping.

METplus Workflow

Beginning time (INIT_BEG): 2021071200

End time (INIT_END): 2021071212

Increment between beginning and end times (INIT_INCREMENT): 6H

Sequence of forecast leads to process (LEAD_SEQ): begin_end_incr(0,30,6)

The following tools are used for each run time:

MTD > RegridDataPlane (via ExtractTiles) > SeriesAnalysis

This example loops by forecast/lead time (with begin, end, and increment as specified in the METplus MTD_SeriesAnalysis_fcstGFS_obsGFS_FeatureRelative_SeriesByLead.conf file). The following list of model initialization and forecast leads are processed in this use case:

Init: 20210712_00Z

Forecast lead: 6, 12, 18, 24, 30

Init: 20210712_06Z

Forecast lead: 6, 12, 18, 24, 30

Init: 20210712_12Z

Forecast lead: 6, 12, 18, 24, 30

METplus Configuration

METplus first loads all of the configuration files found in parm/metplus_config, then it loads any configuration files passed to METplus via the command line.

MET Configuration

METplus sets environment variables based on user settings in the METplus configuration file. See How METplus controls MET config file settings for more details.

YOU SHOULD NOT SET ANY OF THESE ENVIRONMENT VARIABLES YOURSELF! THEY WILL BE OVERWRITTEN BY METPLUS WHEN IT CALLS THE MET TOOLS!

If there is a setting in the MET configuration file that is currently not supported by METplus you’d like to control, please refer to: Overriding Unsupported MET config file settings

Python Embedding

This use case does not use Python embedding.

User Scripting

User Scripting is not used in this use case.

Running METplus

Pass the use case configuration file to the run_metplus.py script along with any user-specific system configuration files if desired:

run_metplus.py /path/to/METplus/parm/use_cases/model_applications/medium_range/MTD_SeriesAnalysis_fcstGFS_obsGFS_FeatureRelative_SeriesByLead.conf /path/to/user_system.conf

#  If the 'convert' executable is not in the user's path, specify the full
#  path to the executable here
#
# * **CONVERT = /usr/bin/convert**
#
# See :ref:`running-metplus` for more information.

Expected Output

A successful run will output the following both to the screen and to the logfile:

INFO: METplus has successfully finished running.

Refer to the value set for OUTPUT_BASE to find where the output data was generated. Output for this use case will be found in series_analysis_lead directory relative to the OUTPUT_BASE, and in the following directories (relative to OUTPUT_BASE):

• series_FHHH

• series_animate

The series_FHHH subdirectory will contain files that have the following format:

OBS_FILES_FHHH

FCST_FILES_FHHH

series_Fhhh_to_FHHH_<varname>_<level>_<stat>.png

series_Fhhh_to_FHHH_<varname>_<level>_<stat>.ps

series_Fhhh_to_FHHH_<varname>_<level>_<stat>.nc

Where:

hhh is the starting forecast hour/lead time in hours

HHH is the ending forecast hour/lead time in hours

varname is the variable of interest, as specified in the METplus series_by_lead_all_fhrs config file

level is the level of interest, as specified in the METplus series_by_lead_all_fhrs config file

stat is the statistic of interest, as specified in the METplus series_by_lead_all_fhrs config file.

The series_animate directory contains the animations of the series analysis in .gif format for all variable, level, and statistics combinations:

series_animate_<varname>_<level>_<stat>.gif
