NWP Containers Online Tutorial | Snow Case (23 Jan 2016) > Run NWP initialization components

Step One (Optional): Run Python to Create Image of Domain

A Python script has been provided to plot the computational domain that is being run for this case. If desired, run the dtcenter/python container to execute Python in docker-space using the namelist.wps in the local scripts directory, mapping the output into the local pythonprd directory.

A successful completion of the Python plotting script will result in the following file in the pythonprd directory. This is the same image that is shown at the top of the page showing the model domain.

Step Two: Run WPS

Using the previously downloaded data (in ${PROJ_DIR}/data), while pointing to the namelists in the local scripts directory, run the dtcenter/wps_wrf container to run WPS in docker-space and map the output into the local wpsprd directory.

Once WPS begins running, you can watch the log files being generated in another window by setting the ${CASE_DIR} environment variable and tailing the log files:

Type CTRL-C to exit the tail utility.

A successful completion of the WPS steps will result in the following files (in addition to other files) in the wpsprd directory

Step Three: Run real.exe

Using the previously downloaded data (in ${PROJ_DIR}/data), output from WPS in step one, and pointing to the namelists in the local scripts directory, run the dtcenter/wps_wrf container to this time run real.exe in docker-space and map the output into the local wrfprd directory. 

The real.exe program should take less than a minute to run, but you can follow its progress as well in the wrfprd directory:

Type CTRL-C to exit the tail utility.

Step One (Optional): Run Python to Create Image of Domain

A Python script has been provided to plot the computational domain that is being run for this case. If desired, run the dtcenter/python container to execute Python in singularity-space using the namelist.wps in the local scripts directory, mapping the output into the local pythonprd directory.

A successful completion of the Python plotting script will result in the following file in the pythonprd directory. This is the same image that is shown at the top of the page showing the model domain.

Step Two: Run WPS

Using the previously downloaded data (in ${PROJ_DIR}/data), while pointing to the namelists in the local scripts directory, run the dtcenter/wps_wrf container to run WPS in singularity-space and map the output into the local wpsprd directory. 

Once WPS begins running, you can watch the log files being generated in another window by setting the ${CASE_DIR} environment variable and tailing the log files:

Type CTRL-C to exit the tail utility.

Step Three: Run real.exe

Using the previously downloaded data (in ${PROJ_DIR}/data), output from WPS in step one, and pointing to the namelists in the local scripts directory, run the dtcenter/wps_wrf container to this time run real.exe in singularity-space and map the output into the local wrfprd directory.

The real.exe program should take less than a minute to run, but you can follow its progress as well in the wrfprd directory:

Type CTRL-C to exit the tail utility.

A successful completion of the WPS steps will result in the following files (in addition to other files) in the wpsprd directory
