Subject: Fwd: MRMS data in MET
From: John Halley Gotway
Time: Thu Feb 23 10:21:47 2017
Hello Russ,
I see you're having trouble using MRMS data in MET. Thanks for
sending a
sample data file.
Good news, I was able to read it using MET version 5.2. I ran the
plot_data_plane utility to plot the values, and I've attached a PNG
version
of the resulting image:
met-5.2/bin/plot_data_plane qpe_24h_20170222_120000.grib2
qpe_24h_20170222_120000.ps 'name="GaugeCorrQPE24H"; level="L0";'
Perhaps you're using an older version of MET and that's the source of
the
problem. MET version 5.2 did include changes to support a much wider
array
of GRIB1 and GRIB2 tables. Here's the release notes:
http://www.dtcenter.org/met/users/support/release_notes/METv5.2_release_notes.php
If you already are using met-5.2 and continue to have problems.
Please let
me know.
Thanks,
John Halley Gotway

Thanks, John! Yes, that command did work — it was the syntax
specifying the vertical level that I guess I wasn’t doing right. It
looks like this method will get us going, but if we run into
additional issues I may be back in touch. Much appreciated!
