Initial Request
----------------------------------------------------------------
To whom it may concern,
I had the following problem pcp_combine. I supplied two input grib files
from WPC and pcp_combine could not read the second one (see output below),
both files came from the ncep site at:
http://ftp.wpc.ncep.noaa.gov/5km_qpf/
Any assistance would be appreciated,

Upon using degrib, noticed that files were in grib2 and give the files
the
correct extensions and did the following pcp_combine:

Hi Brad,
I was writing up a response when I saw your email...
I see that you're having trouble getting pcp_combine to run on some
GRIB
data. As you may have guessed based on the error message, MET is
complaining that you're processing GRIB2 files that are named with a
".grb"
suffix, which it assumes to be GRIB1.
When you pass MET a gridded data file, it needs to figure out how to
process it. The first step is looking at the filename suffix.
Suffixes
like .grb, .grib, and .GRIB are assumed to be GRIB1. Suffixes like
.grb2,
grib2, and .GRIB2 are assumed to be GRIB2. With your data, it's
assumed
your file is GRIB1 because of the .grb suffix. And that's the reason
for
the error.
To get it to work, you could either...
(1) Rename the .grb files to .grib2 ... or ...
(2) Use command line arguments to tell MET that it's really GRIB2.
Here's an example of running MET's plot_data_plane tool, passing to it
a
GRIB2 file that named .grb:
met-6.0/bin/plot_data_plane \
p06m_2017080200f006.grb tmp_p500.ps \
'name="TMP"; level="P500"; file_type = GRIB2;'
The "file_type" option explicitly tells MET to interpret this .grb
file as
a GRIB2 file.

John, thanks for your message and help, I'll keep that around for
reference.
Quick question, have you used matplotlib to plot results of MET or are
you
basically using the MET Viewer?
If you have used matplotlib, if you don't mind I have a couple of
questions, basically about the netcdf file and variables.
Thanks, Brad

Brad,
I have only used "matplotlib" in a class... still spinning up on
python.
But this email is cc'ed to other folks on the MET team. Minna has
done
much more Python plotting than I have and she may be able to answer
your
question. I may be able to answer questions about NetCDF variable
names.
So feel free to shoot.

John
I did'nt see a cc on that last message otherwise I would have sent it
straight to Minna, if you could pass it on it would be appreciated.
Anyway, the issue is this:
In the sample matplotlib code I was using, before calling basemap,
there
was the following:
lon_0 = -nc.variables['true_lon'].getValue()
lat_0 = nc.variables['true_lat'].getValue()
Yet when I did print nc.variables in the python code, there were no
netcdf
variables named true_lon or true_lat.
So a little unsure how to define lat_0, lon_0.

Hi Brad,
>From what I can see, it looks like you are trying to do the correct
thing-
assign a list of longitudes to lon_0 and a list of latitudes to lat_0.
Is
it possible for me to see the rest of your script?
Thanks,
Minna

Subject: problem with pcp_combine
From: Brad Diehl - NOAA Federal
Time: Fri Aug 04 14:07:07 2017
Minna,
Thanks for your help. What I discovered was I cannot do the simplest
plot
in matplotlib, as soon as I call any basemap or even one simple plot
via
plt (see below), it all implodes. Should say I am pretty new to all
this.
With people's help advice, as background info, via minianaconda I
built
matplotlib, python and mpl_toolkits, including basemap. So I'm running
everything in python 2.7. I heard all the buzz about matplotlib and
was
looking forward to using it, but feeling pretty frustrated at this
point.
Any help would be appreciated even though this is not directly related
to
MET.
Thanks, Brad

>>> plt.plot([0, 1, 2, 3, 4], [0, 3, 5, 9, 11])

Subject: problem with pcp_combine
From: Minna Win
Time: Fri Aug 04 15:39:09 2017
Hi Brad,
It looks like something went awry with you package installation. You
might
want to try installing again. There is a conda troubleshooting page
you
might find useful: https://conda.io/docs/troubleshooting.html
One more thing, do you have proj (http://proj4.org/) and GEOS (
https://trac.osgeo.org/geos/) installed-you will need these for
Basemap? A
'conda install' won't be able to install those dependencies for you so
you'll have to install (or have sys admin) install that for you.
Unfortunately, we can't really be of much additional help since this
is not
directly related to MET. Please don't hesitate to contact us if you
have
any further MET related questions.
Best of luck,
Minna

Subject: problem with pcp_combine
From: Julie Prestopnik
Time: Mon Aug 07 13:13:42 2017
I see that you are having some trouble running some files through
pcp_combine. I believe the problem is due to the suffix of thsoe
files.
MET interprets .gb, .grb, and .grib to be GRIB1 files and .gb2, .grb2,
and
.grib2 to be GRIB2 files. So it is trying to read a GRIB2 file as a
GRIB1
files.
When I change the .grb extension to .grb2, I am able to get a
successful
run, however with some WARNING notices:

MET expects the dx and dy values to be the same, however, it looks
like
there are different values for dx and dy in these files. MET also
gives a
warning about multiple GRIB2 table entries matching the lookup
criteria.
Please take a look and verify MET is using the correct one.
I hope that helps!
