Initial Request
----------------------------------------------------------------
Hi MET Help
In MET v5
I believe I need to add my new grid definition to a file called
vx_data_grids
However I cannot find vx_data_grids in my package
Where can I find vx_data_grids in the MET v5 package and it changing it as
simple as using a text editor?
I understand also that after I have changed it I will have to recompile.
Thanks

Lewis,
Users generally do not need to add grid definitions. The only reason
to do
so is to add a convenient way of referring to it by name. Otherwise,
you
can just pass MET the gridded data file, and it'll extract the grid
definition from the file. But if you find it more convenient to add
the
definition, you're more than welcome to do so.
Please take a look in met-
5.1/src/libcode/vx_grid/find_grid_by_name.cc.
You'd add it to one of the arrays of grid definitions in that file
depending on the projection type.
Can you tell me where you saw the reference to "vx_data_grids"? We'll
need
to correct that detail.
Thanks and let us know if any more questions or issues arise.
Thanks,
John Halley Gotway

Hi John
Thanks for your response to my question.
I also thought at first I would not have to add a new grid definition.
I found a reference to this on page B-1 of the MET User guide at:
http://www.dtcenter.org/met/users/docs/users_guide/MET_Users_Guide_v5.0.pdf
In the hope of offering more details
I attach a sample of the two grib files I would like to pass to MET
HOLYROOD_2.5_prog.grib (forecast data)
HOLYROOD_2.5_radar.grib (obs data – from radar)
The attached png image simply shows what the two datasets look like
side by side.
We used an in house program here to derive the details from which our
lat long grid could then be constructed and then we converted this to
GRIB.
When I pass these files to MODE I get the error message:
mode /tmp/afsylpo/15644/HOLYROOD_2.5_prog.grib
/tmp/afsylpo/15644/HOLYROOD_2.5_radar.grib

ERROR :

I may be incorrect here but I was assuming that the above error was
related to a problem with MET recognizing my grid.
I am wondering if you could inspect the attached grib files and help
me determine if they satisfy the criteria for the grids already
defined in MET.
Thanks again for your assistance.

Lewis,
Thanks for sending the sample data files. I'll take a closer look and
see
if I can track down the culprit.
In the meantime, I notice that you haven't filled out the MET
registration
information on our website. We can only provide direct support to
users
who have filled that out to ensure we remain in compliance with the
United
States export compliance laws.
Please go to this page:
http://www.dtcenter.org/met/users/downloads/index.php
Enter your email address in the box at top and hit enter. That will
take
you to the online registration form.
Please write me back when you've finished that and hopefully I'll have
an
answer for you.
Thanks,
John

Hi John
I can confirm that I now filled out the registration form. Note that I
used
my work email address in the form i.e. lewis.poulin at ec.gc.ca since I
will
be using MET in my work related projects with Environment Canada.
Thanks for your help in solving my puzzle as to why it does not work
with
my data. I hope it is easy to fix.

Subject: How do we change vx_data_grids information
From: John Halley Gotway
Time: Thu Oct 29 10:28:02 2015
Lewis,
Great, thanks for registering.
Good news, the problem is simple to fix. These files are in GRIB2
format,
but you've named them using the ".grib" suffix. When MET reads
gridded
data files, it must determine the type of file it's reading. The
first
thing it checks is the suffix of the file. The following are all
interpreted as GRIB1: .grib, .grb, and .gb. While these mean GRIB2:
.grib2, .grb2, and .gb2.
You have 2 choices. You could either rename the files to use a GRIB2
suffix or keep them named this way and explicitly tell MET to
interpret
them as GRIB2 using the "file_type" configuration option.
In the examples below, I used the plot_data_plane tool to plot the
data you
sent me. And you'll see that I've set "file_type = GRIB2;". If you
keep
them named this way, you'll need to add "file_type = GRIB2;" to all
the MET
configuration files (i.e. Grid-Stat, MODE, and so on) that you use:
met-5.1/bin/plot_data_plane \
HOLYROOD_2.5_prog.grib \
HOLYROOD_2.5_prog.ps \
'name="TSTM"; level="A0"; file_type=GRIB2;' \
-plot_range 0 100
met-5.1/bin/plot_data_plane \
HOLYROOD_2.5_radar.grib \
HOLYROOD_2.5_radar.ps \
'name="TSTM"; level="A0"; file_type=GRIB2;' \
-plot_range 0 100
I converted the resulting postscript output to png format and attached
the
images. When trying to get MET to read a particular gridded data
file, I
typically use the plot_data_plane tool to test it out.
Hope that helps.
Thanks,
John

Great - that will be easy to fix. Sorry I had not noticed that in the
documentation. Glad it's an easy one.
Will test drive it soon

Lewis,
Great, thanks for registering.
Good news, the problem is simple to fix. These files are in GRIB2
format,
but you've named them using the ".grib" suffix. When MET reads
gridded
data files, it must determine the type of file it's reading. The
first
thing it checks is the suffix of the file. The following are all
interpreted as GRIB1: .grib, .grb, and .gb. While these mean GRIB2:
.grib2, .grb2, and .gb2.
You have 2 choices. You could either rename the files to use a GRIB2
suffix or keep them named this way and explicitly tell MET to
interpret
them as GRIB2 using the "file_type" configuration option.
In the examples below, I used the plot_data_plane tool to plot the
data you
sent me. And you'll see that I've set "file_type = GRIB2;". If you
keep
them named this way, you'll need to add "file_type = GRIB2;" to all
the MET
configuration files (i.e. Grid-Stat, MODE, and so on) that you use:
met-5.1/bin/plot_data_plane \
HOLYROOD_2.5_prog.grib \
HOLYROOD_2.5_prog.ps \
'name="TSTM"; level="A0"; file_type=GRIB2;' \
-plot_range 0 100
met-5.1/bin/plot_data_plane \
HOLYROOD_2.5_radar.grib \
HOLYROOD_2.5_radar.ps \
'name="TSTM"; level="A0"; file_type=GRIB2;' \
-plot_range 0 100
I converted the resulting postscript output to png format and attached
the
images. When trying to get MET to read a particular gridded data
file, I
typically use the plot_data_plane tool to test it out.
Hope that helps.
Thanks,
John

Time: Thu Oct 29 15:28:48 2015
Thanks John
I did a quick test by renaming the files to have a .grib2 suffix and
it
seems to work fine. This was an easy change for me to do.
Works well.
And thanks for the tip about plot_data. I'll try that also.
