[Met_help] [rt.rap.ucar.edu #92714] History for stat file names

[John Halley Gotway via RT]

----------------------------------------------------------------
  Initial Request
----------------------------------------------------------------

Hi, there,

In relation to the problems I've been having with 1-hr and  8-hr ozone
(with the 1-hr ozone being valid at 05Z and the 8-hr ozone being valid at
12Z - John should remember this problem), I have a question about the
naming of the .stat file here.

Where does the 050000V number come from?  I figure that should be 120000Z
for the 8-hr ozone.  Where is that set in MET (not METplus), and can I
change that in one of the MET config files?

point_stat_CMAQ_AIRNOW_170000L_20191016_050000V.stat

Thanks!

Perry

Hi Perry -

The output filename is created by the build_output_file method in
point_stat.cc,
and the only configurable option available is the prefix CMAQ_AIRNOW.
It seems that method is seeing 05Z as its valid time argument.

John is out until Tuesday of next week ... he should be able to have a
look
at this issue then.

cheers,
David

Hi Perry,

Sorry for the long delay.  It's been a busy couple of days.

David is correct.  MET extracts the valid time from the FIRST FIELD of
data
being evaluated by Point-Stat and uses the timestamp to populate the
output file name.

I tried to log on to tide, but perhaps it's down because it kept
prompting
me for a password.  But I did find some ozone files that I'd pulled
previously.

[johnhg at number5]% ls aqm/aqm.20180325/*8hr*
aqm/aqm.20180325/aqm.t06z.ave_8hr_o3.227.grib2
    aqm/aqm.20180325/aqm.t12z.ave_8hr_o3.227.grib2
aqm/aqm.20180325/aqm.t06z.ave_8hr_o3_bc.148.grib2
 aqm/aqm.20180325/aqm.t12z.ave_8hr_o3_bc.148.grib2
aqm/aqm.20180325/aqm.t06z.ave_8hr_o3_bc.227.grib2
 aqm/aqm.20180325/aqm.t12z.ave_8hr_o3_bc.227.grib2
aqm/aqm.20180325/aqm.t06z.max_8hr_o3.148.grib2
    aqm/aqm.20180325/aqm.t12z.max_8hr_o3.148.grib2
aqm/aqm.20180325/aqm.t06z.max_8hr_o3.227.grib2
    aqm/aqm.20180325/aqm.t12z.max_8hr_o3.227.grib2
aqm/aqm.20180325/aqm.t06z.max_8hr_o3_bc.148.grib2
 aqm/aqm.20180325/aqm.t12z.max_8hr_o3_bc.148.grib2
aqm/aqm.20180325/aqm.t06z.max_8hr_o3_bc.227.grib2
 aqm/aqm.20180325/aqm.t12z.max_8hr_o3_bc.227.grib2

Using wgrib2 to look at one of these:
[johnhg at number5]% wgrib2 -vt
aqm/aqm.20180325/aqm.t06z.max_8hr_o3.148.grib2
1:0:vt=2018032612
2:119985:vt=2018032706

I see that the first record is indeed valid at 12Z.  So I would expect
that
12Z would appear in the output file name.

But the devil is in the details, and we need to look at the specifics.
Are
you able to send me command line call to Point-Stat which results in
the
unexpected file naming conventions, including full paths to files?

If so, I can log on to WCOSS (when it's available) and dive into the
details.

Thanks,
John
