[Met_help] [rt.rap.ucar.edu #77391] History for Problems - (cont)

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

I have a question related to problem mentioned yesterday.  I have Stat files with MPR lines that I am running stat analysis against.   I want stat analysis to apply a vxmask region to the data.  In the MPR lines that statanalysis is reading, the vxmask field is currently set to "Full".  When I run statanal with vxmask set to DST ( my region of interest), it doesn't find any matching lines.  If I run statanal with vxmask set to "Full", it finds the lines.  So vxmask seems to be acting has a filter in statanal instead of a directive to pair down the MPR lines to just the lat lons that fall with in my area of interest.   If I leave the vxmask column blank in the MPR lines, then set the vxmask field to DST in stat analysis, will the software find my MPR lines and properly pair them down to the lat lons that fall within my DST area?

thanks

Hi Bob.

The "-vx_mask" option in STAT-Analysis defines filtering criteria for
the VX_MASK column in the .stat files it reads.

The "-mask_grid" and "-mask_poly" options, for -line_type MPR in your
job entry, define the masking grid or polyline that should be applied
to subset MPR lines prior to computing output statistics.  I suspect
these may be the options you're looking for.

This is mentioned on page 174 of the MET 5.1 user's guide:
   http://www.dtcenter.org/met/users/docs/users_guide/MET_Users_Guide_v5.1.pdf

I hope this helps.

Thanks,
Julie

Stat files with MPR lines that I am running stat analysis against.   I
want stat analysis to apply a vxmask region to the data.  In the MPR
lines that statanalysis is reading, the vxmask field is currently set
to "Full".  When I run statanal with vxmask set to DST ( my region of
interest), it doesn't find any matching lines.  If I run statanal with
vxmask set to "Full", it finds the lines.  So vxmask seems to be
acting has a filter in statanal instead of a directive to pair down
the MPR lines to just the lat lons that fall with in my area of
interest.   If I leave the vxmask column blank in the MPR lines, then
set the vxmask field to DST in stat analysis, will the software find
my MPR lines and properly pair them down to the lat lons that fall
within my DST area?
