Initial Request
----------------------------------------------------------------
I'm having trouble getting ensemble_stat to work. I run it from a batch file and get the following error:
Machine::read() -> unable to open input file "MANPATH=/usr/share/man:/usr/lpp/ssp/man:/usr/lpp/ssp/perl5/man"
I've never seen this error in grid_stat or any other MET routine. Here's the batch file contents:
/sphome/qcteam/METv3.0/bin/ensemble_stat 10 /h/data/global/WXQC/data/met/cfg/ensemble/ens_files.txt /h/data/global/WXQC/data/met/cfg/ensemble/ensemble_stat_cfg.default -point_obs /h/data/global/WXQC/data/obs_prep/2011030918 -outdir /h/data/global/WXQC/data/met/stats/ensemble -v 2
And ens_files.txt contains my file names, each of the 10 space delimited. The observation file is the NetCDF version of the PrepBufr formatted observation data from NCEP, converted via pb2nc.
Any thoughts as to what portion of MET might be throwing out the PATH variable issue? That doesn't sound like anything ensemble_stat would worry about.
Thanks,
Matt

Matt,
Please try running the following command instead:
/sphome/qcteam/METv3.0/bin/ensemble_stat
/h/data/global/WXQC/data/met/cfg/ensemble/ens_files.txt
/h/data/global/WXQC/data/met/cfg/ensemble/ensemble_stat_cfg.default
-point_obs
/h/data/global/WXQC/data/obs_prep/2011030918 -outdir
/h/data/global/WXQC/data/met/stats/ensemble -v 2
Notice that I've removed the "10" from the command line. You can
specify the ensemble files in one of two ways:
(1) As "n_ens ens_file_1 ... ens_file_n" which is the number of files
followed by the file names themselves
(2) Or as "ens_file_list" which is an ASCII file containing the list
of file names
You're mixing the two of those methods together. And looking at the
usage statement for Ensemble-Stat, I see why. Here's a subset of it:
Usage: ensemble_stat
n_ens ens_file_1 ... ens_file_n | ens_file_list
where "n_ens" is the number of ensemble members (required).
"ens_file_1 ... ens_file_n" is a list of ensemble
member file names (required).
"ens_file_list" is an ASCII file containing a list of
ensemble member file names (required).
I see why this setting is confusing. I could change it to look like
this:
Usage: ensemble_stat
n_ens ens_file_1 ... ens_file_n | ens_file_list
where "n_ens ens_file_1 ... ens_file_n" is the number of
ensemble members followed by a list of ensemble member file names
(required).
"ens_file_list" is an ASCII file containing a list of
ensemble member file names (required).
That would probably be more clear.
Please let me know if removing "10" does the trick for you.
Thanks,
John

That solved the problem-thanks John!
Note that I actually got 2
e-mails from you, so the met_help address works... sometimes!?
You're right on the documentation; I read that n_ens was required, and
took the '|' to mean that it was either a list of file names OR a text
file, but either way I had to explicitly state the number of files to
be read in. That section of 3.9.1 is a bit confusing since it says 4
arguments are required, but the nature of them depends on how the list
of files is passed. Far be it for me to comment on a User's Guide...
:) But I *do* read them and wonder if I find something confusing
that others may be confused too.

Matt,
Great, glad that did the trick. And really, thanks for the feedback
about the user's guide. I've made notes about the 3 issues you
pointed out and will fix them shortly. We appreciate it.
I'll go ahead and resolve this ticket. But please let us know if more
issues/questions come up in your use of MET.
Thanks,
John

Matt,
Please try changing "fcst_field[] = [ "TMP/L2" ];" to "fcst_field[] =
[ "TMP/Z2" ];". I know this is a very minor change but changing the
'L' to a 'Z' triggers a different set of logic in the code.
Namely, when you put 'Z2', that tells the code that this is really a
surface variable and should be matched up with observations of type
ADPSFC. Hopefully that'll get you matched pairs. Generally,
you should use 'Z2' to specify 2-meter fields (like TMP or specific
humidity) and 'Z10' for 10-meter winds. And use a 'P' to specify
pressure levels, like 'P500' for 500mb fields. The 'L' is used as
a "generic" level type - so it doesn't kick off the special processing
for surface fields.
Clear as mud!?
We do have an anonymous FTP site to which you could post data, but
perhaps we've already tried this. The instructions for posting to it
can be found here:
http://www.dtcenter.org/met/users/support/met_help.php#ftp
But I'm guessing your security rules will prevent you from accessing
that site.
Thanks,
John

Bob Craig's NetCDF data, brought down from NCEP and converted via
pb2nc. When I run ensemble_stat it throws all of my observations and
all I get is a header output file with no actual numbers. The poly
mask I am using is CONUS, which is also the domain of the ensemble so
there should be something available after the poly mask is applied.
Bob uses the same files in point_stat and it works just fine... so I
can't figure out where I've made a mistake. Excerpts from the log
file:

> I know from doing an 'ncdump' on the data file and examining its
contents that there are ADPSFC records in the file. What I'm unclear
on is if I have not set the obs_field[] array in the config file
correctly. The forecasts are GriB data, but the obs are NetCDF. I
set it as you see below to follow what Bob said worked when he ran
point_stat with it. I've been confused by the explanation of how to
set the items in parentheses for NetCDF cases ever since I first read
it, since I and j aren't intuitive at all. What dimensions do they
refer to if the last two (*,*) are the grid dimensions? Well, that is
*if* it is gridded, because this file is not, thus I use the
-point_obs option in the command line.

while I could e-mail it for you to test, I have no idea if AFWA will
properly send it to you through e-mail. This is where we really could
use a reliable FTP connection between AFWA and NCAR to transfer some
files, but as you know most of this is done via sending DVDs in the
mail... frustrating. Because I fear without you running all of the
files I have, we're really not replicating the error with the full
suite of files, config, model and obs, that I'm requesting be used in
my command line.

Once again, that did the trick! You're pretty good at this MET
stuff...
What we do here to extract GriB fields is simply key on
the kpds5, 6 and 7 values for each record and equate a variable and
pressure level to a set of kpds5/6/7 values, since sometimes they
differ from model to model (e.g., precip is 61 or 240)... I was hoping
I could explicitly state them in some way to distinguish from surface
temperature vs. the 2-meter value. I hoped L2 was specifically
controlling kpds7 when I invoked it. I guess not!
Hey, the FTP
seemed to work! I put 4 simple files (config stuff) out there to see
if you can view them on your end in a 'sittel_data' directory. Let me
know if you can see them, and we'll be able to use that should we need
to exchange files.

Matt,
Please try changing "fcst_field[] = [
"TMP/L2" ];" to "fcst_field[] = [ "TMP/Z2" ];". I know this is a very
minor change but changing the 'L' to a 'Z' triggers a different set of
logic in the code.
Namely, when you put 'Z2', that tells the code
that this is really a surface variable and should be matched up with
observations of type ADPSFC. Hopefully that'll get you matched pairs.
Generally,
you should use 'Z2' to specify 2-meter fields (like TMP or
specific humidity) and 'Z10' for 10-meter winds. And use a 'P' to
specify pressure levels, like 'P500' for 500mb fields. The 'L' is
used as
a "generic" level type - so it doesn't kick off the special
processing for surface fields.
Clear as mud!?
We do have an
anonymous FTP site to which you could post data, but perhaps we've
already tried this. The instructions for posting to it can be found
here:
http://www.dtcenter.org/met/users/support/met_help.php#ftp
But I'm guessing your security rules will prevent you from accessing
that site.
Thanks,
John

figure out with ensemble_stat. I'm using Bob Craig's NetCDF data,
brought down from NCEP and converted via pb2nc. When I run
ensemble_stat it throws all of my observations and all I get is a
header output file with no actual numbers. The poly mask I am using is
CONUS, which is also the domain of the ensemble so there should be
something available after the poly mask is applied. Bob uses the same
files in point_stat and it works just fine... so I can't figure out
where I've made a mistake. Excerpts from the log file:

on is if I have not set the obs_field[] array in the config file
correctly. The forecasts are GriB data, but the obs are NetCDF. I
set it as you see below to follow what Bob said worked when he ran
point_stat with it. I've been confused by the explanation of how to
set the items in parentheses for NetCDF cases ever since I first read
it, since I and j aren't intuitive at all. What dimensions do they
refer to if the last two (*,*) are the grid dimensions? Well, that is
*if* it is gridded, because this file is not, thus I use the
-point_obs option in the command line.

through e-mail. This is where we really could use a reliable FTP
connection between AFWA and NCAR to transfer some files, but as you
know most of this is done via sending DVDs in the mail... frustrating.
Because I fear without you running all of the files I have, we're
really not replicating the error with the full suite of files, config,
model and obs, that I'm requesting be used in my command line.

You're right on the documentation; I read that n_ens was required, and
took the '|' to mean that it was either a list of file names OR a text
file, but either way I had to explicitly state the number of files to
be read in. That section of 3.9.1 is a bit confusing since it says 4
arguments are required, but the nature of them depends on how the list
of files is passed. Far be it for me to comment on a User's Guide...
:) But I *do* read them and wonder if I find something confusing
that others may be confused too.

Matt,
Yep, I see them in
ftp.rap.ucar.edu/incoming/irap/met_help/sittel_data. So we should be
able to use that for exchanging data.
As for distinguishing between 2-meter temperature and surface
temperature, try using "TMP/Z2" for the former and "TMP/Z0" for the
latter. I think that'd do the trick for picking out the input fields.
The problem though is that we really don't have a way of filtering
the point observations to distinguish between 2-meter temp and surface
temp. My understanding is that the ADPSFC observations of
temperature are all really 2-meter temperature.
But the "TMP/Z2" and "TMP/Z0" thing should allow you to distinguish
the gridded fields in MET - perhaps when you're running Grid-Stat or
MODE. FYI, when you're setting up these MET tasks to run
initially, try using "-v 3" or "-v 4" on the command lines. That'll
increase the level of logging. You'll be able to explicitly see which
GRIB records the MET tool is reading, and you can verify
that it's using the ones you intended.
Thanks,
John
