[Met_help] [rt.rap.ucar.edu #86849] History for Question on using Point_Stat with already matched paired file

[John Halley Gotway via RT]

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

Hi,

I have acquired a new ASCAT file that already contains matched pairs of
surface wind speed with the GFS that have been time and spatially
interpolated (resolution of 3 minute time steps).  These are in a single
file, that could first be read in using python.

Can I use this single file to generate the statistics that Point_Stat gives
me, since this requires a point file and a gridded file?  Would a different
MET tool work better?

Thanks!

Roz

Hi Roz,

Unfortunately, no.  There is currently no entry point into the
STAT-Analysis tool using Python.  The met-8.0 release will include the
ability to configure MET to call a Python script to read a single 2D
plane
of gridded data.

We have already talked about how we could enhance STAT-Analysis to a
call a
Python script to load up matched pair data.   This was in the context
of
Space Weather Verification.  Sounds like this functionality would be
useful
to you as well.

The obvious way of using this paired ASCAT data would be to...
(1) Reformat that paired data to make it look like the MPR line.
(2) Run Stat-Analysis to aggregate these MPR lines and compute
whatever
aggregations and statistics you'd like.

Thanks,
John

Hi John,

Ok, writing the data out in the MPR format is doable.  I do that
something
similar with my ASCAT binary file, to put it in a format that can be
used
with ASCII2NC.  So, I could use the same methodology to write out this
other dataset, then process it with STAT-Analysis.

Thanks for letting me know.  That's all I needed to know.  You can
close
the ticket.  :-)
