[Met_help] MET 2.0

[John Halley Gotway]

Ruifang,

I believe this is really more of an issue with the WRF Post-Processor.  It
was setting the scan mode flag incorrectly when creating the output GRIB
file.  I asked a wrf-help support person, and she suggested that I have
you write wrf-help about the issue.  She believes that it's already been
fixed - especially in the 3.1 version that is being released today.

If you're planning to upgrade to WRF version 3.1, I'd suggest trying the
WPP included with 3.1.  If not, you can contact wrf-help about it.  In
particular, they'll need to see your copy of the file named INITPOST.f for
ARW or INITPOST_NMM.f if you're running NMM.

Hope that helps.
