Point-Stat Tool: Run

Next, run Point-Stat to compare a GRIB forecast to the NetCDF point observation output of the ASCII2NC tool. Run the following command line:

Point-Stat is now performing the verification tasks we requested in the configuration file. It should take less than a minute to run. You should see several status messages printed to the screen to indicate progress.

Now try rerunning the command listed above, but increase the verbosity level to 3 (-v 3). Notice the more detailed information about which observations were used for each verification task. If you run Point-Stat and get fewer matched pairs than you expected, try using the -v 3 option to see why the observations were rejected.

Users often write MET-Help to ask why they got zero matched pairs from Point-Stat. The first step is always rerunning Point-Stat using verbosity level 3 or higher to list the counts of reasons for why observations were not used!
