[Met_help] [rt.rap.ucar.edu #89808] History for override of ens_ssvar_bin_size

Fri Apr 19 08:33:00 MDT 2019

----------------------------------------------------------------
  Initial Request
----------------------------------------------------------------

For our current scoring, we really need the following ensemble_stat config 
parameter to create 1 bin versus automated adjustment.

ens_ssvar_bin_size = 1.0;

WARNING:
WARNING: PairDataEnsemble::compute_ssvar() -> writing at least 1000 SSVAR 
output lines. Increase the ssvar_bin_size config file setting for this 
variable to reduce the number of variance bins.

We see in the documentation for MET-8.0 UM that the software will make an 
adjustment if the software believes the bin size is too small. Is there a way 
we can override to force 1 bin?

Thanks,
Glen

Hi Glen,

The ens_ssvar_bin_size config file option relates to the SSVAR output
generated by Ensemble-Stat.  The intention of this is to group points
into
separate bins based on the ensemble spread for each point.  The
default bin
size is set to 1.0.  As ensemble-stat runs, it adds bins as needed to
capture the range of ensemble spread values encountered.

We added a warning message so that when you produce more than 1000
bins,
you should consider increasing the bin size so that the resulting
number of
bins is smaller.

If you really only want one bin, just set the ens_ssvar_bin_size very,
very
large:
ens_ssvar_bin_size = 1000000;

If the bin SIZE is huge then the NUMBER of bins will be only 1.

Make sense?

Thanks,
John
