Postprocess NWP Data
After the WRF model is run, the output is run through the Unified Post Processor (UPP) to interpolate model output to new vertical coordinates, e.g. pressure levels, and compute a number diagnostic variables that are output in GRIB2 format.
SELECT THE APPROPRIATE CONTAINER INSTRUCTIONS FOR YOUR SYSTEM BELOW:
Using the previously created WRF netCDF data in the wrfprd directory, while pointing to the namelist in the local scripts directory, run the dtcenter/upp container to run UPP in docker-space to post-process the WRF data into grib2 format, and map the output into the local postprd directory:
-v ${PROJ_DIR}/container-dtc-nwp/components/scripts/common:/home/scripts/common \
-v ${PROJ_DIR}/container-dtc-nwp/components/scripts/derecho_20120629:/home/scripts/case \
-v ${CASE_DIR}/wrfprd:/home/wrfprd -v ${CASE_DIR}/postprd:/home/postprd \
--name run-derecho-upp dtcenter/upp:${PROJ_VERSION} /home/scripts/common/run_upp.ksh
As UPP is run the post-processed GRIB output files will appear in the postprd/. Please review the contents of those directories to interrogate the data.
UPP runs quickly for each forecast hour, but you can see the log files generated in another window by setting the ${CASE_DIR} environment variable and tailing the log file:
Type CTRL-C to exit the tail.
A successful completion of the UPP step will result in the following files (in addition to other files) in the postprd directory:
wrfprs_d01.03
wrfprs_d01.06
...
wrfprs_d01.21
wrfprs_d01.24
wrfprs_d02.15
wrfprs_d02.18
wrfprs_d02.21
Using the previously created netCDF wrfout data in the wrfprd directory, while pointing to the namelists in the local scripts directory, create a container using the upp image to run WRF in singularity-space and map the output into the local postprd directory:
