[Met_help] [rt.rap.ucar.edu #88013] History for Matching forecasts among many models in MET-TC

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

Hello,

I am trying to use MET-TC to compare the skill of several models over 3
years.  I have noticed that in my tc_stat output there are different
numbers of cases (forecasts) used in the verification for each model.  I
believe it is standard to only compare forecasts that are present in all
model being compared, to be fair.  Is there a way in tc_pairs or tc_stat to
make sure that I am only using tracks present for all models?

Thank you,
Shannon

I saw that in the MET 7.0 manual there is a figure showing
"homogeneous" TC
intensity comparisons, however no mention of how to achieve that in
the
MET-TC tools section.  Is there an off-line script that can be used to
homogenize the sample size among models or does every user just make
their
own script to do this?

Shannon,

I see that you have a question about how to produce a homogeneous
sample of
data for the MET-TC data.  This is done using the "event_equal" flag
in the
TC-Stat configuration file.  Here's a selection from the file
met-7.0/share/met/config/README_TC, which is also included in the
user's
guide:

//
// Specify whether only those cases common to all models in the
dataset
should
// be retained.  May modify using the "-event_equal" job command
option.
//
// e.g. event_equal = FALSE;
//
event_equal = FALSE;

We have also included a sample R plotting script in
met-7.0/share/met/Rscripts/plot_tcmpr.R.  This R-script does 2 main
things...
- take the user-specified command line filtering options to call the
TC-Stat tool to filter the input data
- create one or more plots of the resulting filtered data

If you're running that R-script then "event_equal = TRUE" by default.
But
the "-no_ee" command line option can be used to switch it back to
false.

Hope that helps clarify.

Thanks,
John Halley Gotway

John,

Thanks for the explanation.  That makes it easy!  I guess I was only
looking for options in the tc_pairs tool.

Sure thing.  I'll go ahead and resolve the ticket.  But just let us
know
what other questions or issues arise.

Thanks,
John
