Ensemble-Stat Tool: General
Ensemble-Stat Functionality
The Ensemble-Stat tool may be used to verify the deterministic ensemble members against gridded and/or point observations. Statistics are then derived using those observations, such as rank histograms, probability integral transform histograms, spread/skill variance, relative position and continuous ranked probability score.
Ensemble-Stat Usage
View the usage statement for Ensemble-Stat by simply typing the following:
At a minimum, the input gridded ensemble files and the configuration config_file must be passed in on the command line. You can specify the list of ensemble files to be used either as a count of the number of ensemble members followed by the file name for each (n_ens ens_fil e_1 ... ens_file_n) or as an ASCII file containing the names of the ensemble files to be used (ens_file_list). Choose whichever way is most convenient for you. The optional -grid_obs and -point_obs command line options may be used to specify gridded and/or point observations to be used for computing rank histograms and other ensemble statistics.
As with the other MET statistics tools, all ensemble data and gridded verifying observations must be interpolated to a common grid prior to processing. This may be done using the automated regrid feature in the Ensemble-Stat configuration file or by running copygb and/or wgrib2 first.
