This is the system-specific configuration file for the NCAR Yellowstone cluster. It should not be used directly. Users should copy it to parm/system.conf and edit the values manually.

This is a configuration override file. This file sets options in the following sections:

[config] — Sets basic configuration options used by all components.
[dir] — Configure directory paths.
[holdvars] — Holdvars variable generation section. This sets variables that are only used to create the holdvars file for ksh. Nothing in this section is ever used by the Python code. That vestigial file is just for compatibility with legacy external workflows, and it will be removed eventually. The external workflows that need it are: HHS - to decide whether things failed graphics scripts - for data paths Note that you must also edit parm/hwrf_holdvars.txt in order for the values in this section to be sent to the holdvars.txt file.
[runwrf] — This section is read by the script that runs the WRF forecast job at 2km. It is not used by other executions of wrf. See runwrf3km for the 3km configuration.
[wrfexe] — This section is read by all scripts that run the wrf or nmm_real.

Section [runwrf]

This section is read by the script that runs the WRF forecast job at 2km. It is not used by other executions of wrf. See runwrf3km for the 3km configuration.

See the main documentation for [runwrf] for details.
