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

Hi
I had install the METV3.0 on our IBM machine.  I like to calculate the
ETS, Threat scores,Biases and Root Mean square error.

1)Can anyone please give a followup to do this for WRF-NMM out against
its own analysis.

2)I could install the MET using the WRF-ARW.  Will the executable thus
generate work for statistics of WRF-NMM also or should I compile
seperatly for WRF-NMM also.

Thanks
Ratna

Ratna,

While MET may be used to verify NWP forecasts produced by WRF, it
really is not tied to WRF in the way you think.  You don't need to
compile it "for ARW" or "for NMM".  You just compile MET once and
use it verify whatever data you have.  The big caveat is that before
verifying your WRF output with MET, you must first post-process it.
You can either post-process it using the WRF-ARW pinterp tool
or the WRF Post-Processor (WPP) which can be run on WRF-ARW or WRF-NMM
output.

I'd strongly encourage you to use WPP instead of pinterp since MET
provides better support for the GRIB output of WPP than the NetCDF
output of pinterp.

If you're just getting started with MET, let me refer you to:
(1) The MET User's Guide:
   http://www.dtcenter.org/met/users/docs/overview.php
(2) The MET Online Tutorial:
   http://www.dtcenter.org/met/users/support/online_tutorial/METv3.0/index.php

The latest version of MET is METv3.0.1, but the tutorial is for
METv3.0.  Anywhere you see METv3.0 in the tutorial, just substitute in
METv3.0.1.  I'd suggest stepping through the tutorial which gives
you a lot of help compiling MET and getting started with it.

Hope that helps.
