End of Practical Session 2

Congratulations! You have completed Session 2!

If you have extra time, you may want to try this additional METplus exercise.

The default statistics created by this use case only dump the partial sums, so we will be also modifying the MET configuration file to add the continuous statistics to the output. There is a little more setup in this use case, which will be instructive and demonstrate the basic structure, flexibility and setup of METplus configuration.

Instructions: Copy and modify the METplus configuration file for Upper Air to write Continuous statistics (cnt) and the Vector Continuous Statistics (vcnt) line types to both the stat file and its own file.
Copy the PointStat.conf file to the user_config directory.
cp ${METPLUS_BUILD_BASE}/parm/use_cases/met_tool_wrapper/PointStat/PointStat.conf \
${METPLUS_TUTORIAL_DIR}/user_config/PointStat_add_linetype.conf
Edit the file to remove the # character from the beginning of the variables (this uncomments the line) and set the values to BOTH.
Change this line (around line 68):
#POINT_STAT_OUTPUT_FLAG_CNT =

to

POINT_STAT_OUTPUT_FLAG_CNT = BOTH
and change this line (around line 73):
#POINT_STAT_OUTPUT_FLAG_VCNT =

to

POINT_STAT_OUTPUT_FLAG_VCNT = BOTH
vi ${METPLUS_TUTORIAL_DIR}/user_config/PointStat_add_linetype.conf
Rerun METplus and use config.OUTPUT_BASE to change the output directory from the command line:
run_metplus.py \
${METPLUS_TUTORIAL_DIR}/user_config/PointStat_add_linetype.conf \
${METPLUS_TUTORIAL_DIR}/tutorial.conf \
config.OUTPUT_BASE=${METPLUS_TUTORIAL_DIR}/output/PointStat_AddLinetype
Review the additional output files generated under ${METPLUS_TUTORIAL_DIR}/output/PointStat_AddLinetype/point_stat
point_stat_360000L_20070331_120000V.stat
point_stat_360000L_20070331_120000V_cnt.txt
point_stat_360000L_20070331_120000V_vcnt.txt
Open the stat file and notice there are two more linetypes, cnt and vcnt.
