Use Case: Feature Relative
Use Case: Feature Relative cindyhg Mon, 06/24/2019 - 14:34METplus Use Case: Feature Relative (Series-Analysis by init)
Setup
In this exercise, you will perform a series analysis based on the init time of your sample data. This use case utilizes the MET Tc-Pairs, Tc-Stat, and Series-Analysis tools, and the METplus wrappers: TcPairs, ExtractTiles, TcStat, and SeriesByInit. Please refer to the MET User's Guide for a description of the MET tools and the METplus Users Guide for more details about the wrappers. Please note that the METplus User's Guide is a work-in-progress and may have missing content.
Create Custom Configuration File
Define a unique directory under output that you will use for this use case. Create a configuration file to override OUTPUT_BASE to that directory.
Set OUTPUT_BASE to contain a subdirectory specific to the Feature Relative use case. Make sure to put it under the [dir] section.
OUTPUT_BASE = {ENV[METPLUS_TUTORIAL_DIR]}/output/feature_relative
to keep this feature relative output separate from the other examples.
Using this custom configuration file and the Feature Relative use case configuration files that are distributed with METplus, you should be able to run the use case using the sample input data set without any other changes.
Review Use Case Configuration File: feature_relative.conf
View the file and study the configuration variables that are defined.
Note that variables in feature_relative.conf reference other variable you defined in other configuration files.
For example:
This references OUTPUT_BASE which you set in the METplus system configuration file (metplus_config/metplus_system.conf). METplus config variables can reference other config variables, even if they are defined in a config file that is read afterwards.
Run METplus
Run the following command:
You will see output streaming to your screen. This may take up to 4 minutes to complete. METplus is finished running when control returns to your terminal console and you see the following text:
Review the Output Files
You should have output files in the following directories from the intermediate wrappers TcPairs, ExtractTiles, and TcStat, respectively:
extract_tiles
series_init_filtered
and the output of interest, from the SeriesByInit wrapper:
which has a directory corresponding to the date(s) of data in the data window:
and under that directory are subdirectories named by the storm:
ML1200972014
ML1200992014
ML1201002014
ML1201032014
ML1201042014
ML1201052014
ML1201062014
ML1201072014
ML1201082014
ML1201092014
ML1201102014
and under each of those directories lies the files of interest:
FCST_ASCII_FILES_ML1200942014
series_TMP_Z2_FBAR.png
series_TMP_Z2_FBAR.ps
series_TMP_Z2_ME.png
series_TMP_Z2_ME.ps
series_TMP_Z2.nc
series_TMP_Z2_OBAR.png
series_TMP_Z2_OBAR.ps
series_TMP_Z2_TOTAL.png
series_TMP_Z2_TOTAL.ps
The ANLY_ASCII_FILES_ML########## (where ########## is the storm) is a text file that contains a list of the analysis data included in the series analysis. The FCST_ASCII_FILES_ML########## (where ########## is the storm) is a text file that contains a list of forecast data included in the series analysis.
The .nc files are the series analysis output generated from the MET series_analysis tool.
The .png and .ps files are graphics files that can be viewed using display or ghostview, respectively:

Review the Log File
A log file is generated in your logging directory: ${METPLUS_TUTORIAL_DIR}/output/feature_relative/logs. The filename contains the timestamp corresponding to the current day. To view the log file:
Review the Final Configuration File
The final configuration file is metplus_final.conf. This contains all of the configuration variables used in the run.
Use Case: Feature Relative
Use Case: Feature Relative cindyhg Mon, 06/24/2019 - 14:36METplus Use Case: Feature Relative (Series-Analysis by lead, by forecast hour grouping)
Setup
In this exercise, you will perform a series analysis based on the lead time (forecast hour) of your sample data and organize your results by forecast hour groupings. This use case utilizes the MET Tc-Pairs, Tc-Stat, and Series-Analysis tools, and the METplus wrappers: TcPairs, ExtractTiles, TcStat, and SeriesByLead. Please refer to the MET User's Guide for a description of the MET tools and the METplus Users Guide for more details about the wrappers. Please note that the METplus User's Guide is a work-in-progress and may have missing content.
Create Custom Configuration File
Define a unique directory under output that you will use for this use case. Create a configuration file to override OUTPUT_BASE to that directory.
Set OUTPUT_BASE to contain a subdirectory specific to the Series by Lead use case. Make sure to put it under the [dir] section.
OUTPUT_BASE = {ENV[METPLUS_TUTORIAL_DIR]}/output/series_by_lead_fhr_grouping
to keep this feature relative output separate from the other examples.
Using this custom configuration file and the Feature Relative use case configuration files that are distributed with METplus, you should be able to run the use case using the sample input data set without any other changes.
Review Use Case Configuration File: series_by_lead_by_fhr_grouping.conf
View the file and study the configuration variables that are defined.
Note that variables in series_by_lead_fhr_grouping.conf reference other variable you defined in your mycustom.conf configuration file.
For example:
This references OUTPUT_BASE which you set in the METplus system configuration file (metplus_config/metplus_system.conf). METplus config variables can reference other config variables, even if they are defined in a config file that is read afterwards.
Run METplus
Run the following command:
-c use_cases/feature_relative/examples/series_by_lead_by_fhr_grouping.conf \
-c user_config/sbl.output.conf
You will see output streaming to your screen. This may take up to 3 minutes to complete. When it is complete, your prompt returns.
Review the Output Files
You should have the following output directories that result from running the wrappers TcPairs, ExtractTiles, and TcStat, respectively:
extract_tiles
series_lead_filtered
and the output directory of interest, from the SeriesByLead wrapper:
That directory contains the following directories:
Day2
Day3
series_animate
Day1 contain the following files:
series_F000_to_F018_TMP_Z2_ME.png
series_F000_to_F018_TMP_Z2_OBAR.ps
FCST_FILES_F000_to_F018
series_F000_to_F018_TMP_Z2_ME.ps
series_F000_to_F018_TMP_Z2_TOTAL.png
series_F000_to_F018_TMP_Z2_FBAR.png
series_F000_to_F018_TMP_Z2.nc
series_F000_to_F018_TMP_Z2_TOTAL.ps
series_F000_to_F018_TMP_Z2_FBAR.ps
series_F000_to_F018_TMP_Z2_OBAR.png
The ANLY_FILES_F000_to_F018 is a text file that contains a list of the data that is included in the series analysis.
Day2 contains equivalent files for forecast leads 24 to 42 and Day3 contains equivalent files for forecast leads 48 to 66.
The .nc files are the series analysis output generated from the MET Series-Analysis tool.
