Output

As mentioned previously, Gen-Ens-Prod only produces 1 netCDF output file. This file contains all of the requested products that were made in the configuration file.

Let's take a look at the contents of the file:

ncdump -h GenEnsProd_APCP24.nc

Note that the file contains 9 variables: the latitude and longitudes, the ensemble mean and standard deviation, the ensemble valid data count, and the four categorical thresholds that were set, all with the prefix APCP_24_A24_ENS_FREQ_. These thresholds act as uncalibrated probability forecasts and can be verified against observational datasets with other MET tools.

Now let's visually inspect the file contents with a graphical viewer:

ncview GenEnsProd_APCP24.nc

Click through the variable names in the ncview window to see plots of the content we saw in the ncdump command.

Now that we've seen a successful run of the Gen-Ens-Prod tool, let's change the run command slightly to show how the -ctrl setting works.
