The default value is currently /tmp, however some machines discourage using this directory to write temp files. When running through METplus wrappers, the environment variable MET_TMP_DIR is set which overrides this value. Running with the wrapped MET config files outside of the wrappers (via command line) require the other environment variables to be set to run or it will fail. If all of the env vars set for a command are set, then it will include MET_TMP_DIR, however this may not always be the case. Setting the value for tmp to $(MET_TMP_DIR) will ensure that the value is overridden properly when running by hand and make it clear to users that the value set for tmp in those files is not being used.

Describe the Enhancement

Change the files in parm/met_config to reference the MET_TMP_DIR environment variable instead of /tmp.
