[Met_help] [rt.rap.ucar.edu #84708] History for WDIR MPR lines

Wed Apr 25 08:53:10 MDT 2018

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

Good morning, 

I would like to find out if there is a way to generate MPR lines for WDIR.
I've been able to make MPR lines for WIND with point_stat, and aggregated
stats for WDIR with stat_analysis, but not simply a file of matched pairs
for WDIR.  It seems like it would be a simple task, given that stat_analysis
can already read the UGRD and VGRD pairs and calculate the statistics.
Hopefully it's just something I'm overlooking?  Thanks for the assistance.

Hi Jeff.

I'm not sure if you will receive my original message or not (see
below).
The files I attached were too large, and I just received a
notification of
that.  I ran gzip on each of the files and put them into the attached
tar
file for you.

Julie,

Thank you for the response.  So basically what I need to do is add as
many
header variables to the '-by' section as I need to make the
observations
unique?

I will attempt to use this technique with "-by
MODEL,FCST_LEAD,OBS_VALID_BEG,INDEX,OBS_SID,OBS_LVL" and see if this
gives me
what I need, and then I'll get back to you.

Yes, exactly.  You can use the "-by" section to narrow down what you
need
to in order to make the observations unique.  Please do let us know
how it
goes.
