Everything needed to set up EMC_verif-global to run standalone will be contained in the your clone from GitHub.

1. Set up configuration file

The default configuration file for EMC_verif-global is parm/config/config.vrfy. It is recommended that users create a copy or copies of this configuration file for their own verification purposes. The user customized configuration file(s) can live wherever and be named whatever a user desires.

Below is a more in-depth description of the settings in the configuration file.

The first section contains switches for the verification cases that can be run. The setting "YES" will run the verification. The setting "NO" will not run the verification. Switches with "STEP1" at the end (RUN_GRID2GRID_STEP1, RUN_GRID2OBS_STEP1, RUN_PRECIP_STEP1, RUN_SATELLITE_STEP1) are for commuting various statistics, and switches with "STEP2" at the end (RUN_GRID2GRID_STEP2, RUN_GRID2OBS_STEP2, RUN_PRECIP_STEP2, RUN_SATELLITE_STEP2) are for creating plots. In order to run the "STEP2" switches, the corresponding "STEP1" switch will have needed to be run prior.

    RUN_GRID2GRID_STEP1: grid-to-grid verification statistics production (default: YES)
    RUN_GRID2GRID_STEP2: grid-to-grid verification statistics graphics production (default: NO)
    RUN_GRID2OBS_STEP1: grid-to-obs verification statistics production (default: YES)
    RUN_GRID2OBS_STEP2: grid-to-obs verification statistics graphics production (default: NO)
    RUN_PRECIP_STEP1: precipitation verification statistics production (default: YES)
    RUN_PRECIP_STEP2: precipitation verification statistics graphics production (default: NO)
    RUN_SATELLITE_STEP1: satellite verification statistics production (default: NO)
    RUN_SATELLITE_STEP2: satellite verification statistics graphics production (default: NO)
    RUN_TROPCYC: tropical cyclone verification statistics graphics production (default: NO)
    RUN_MAPS2D: latitude-longitude and zonal mean graphics comparing variables amongst models (default: NO)
    RUN_MAPSDA: latitude-longitude and zonal mean graphics comparing variables for increments and ensemble mean and spread amongst models (default: NO)

Then, follows a section of settings that generally apply to running all the verification types.

Finally, each verification type/switch has its own section of settings specifically related to it.

2. Run

To run, from the top directory users will move to the ush directory. Here is the script run_verif_global.sh that runs EMC_verif-global. It takes one run time argument which is the path to the configuration file that the user wishes to run with. If none is given it will default to using config.vrfy. And example run time command may look like below

$ ./run_verif_global.sh ../parm/config/config.vrfy.example
