[Met_help] [rt.rap.ucar.edu #83164] History for intermediate MET files to view vx masks

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

Hi Met Help,

I've created my own MET vx masks and I am trying to double check they are
working as I would expect them to when MET is run (I have already made the
.ps plots to view the area). Jacob Carley (cc'd) mentioned that MET should
have the capability to output some intermediate NetCDF files that I should
be able to view the masked region using the plot_data_tool. My MET jobs was
run on WCOSS (gyre) here:
/gpfs/gd3/stmp/Donald.E.Lippi/tmpnwprd/rw_c005/namrr_metradar_conus_f36.tm00_12

But I do not see any NetCDF output for this run. Is there an option to
write out this intermediate file so that I can double check my masks?

Thank you,
Donnie

Donnie,

I see that you're running MET using some verification masking regions
that
you generated yourself.

Based on your description, I assume that Jacob is referring to the
NetCDF
matched pairs output from the Grid-Stat tool.  When you run Grid-Stat,
you
can set up the nc_pairs_flag config file option to dump out gridded
fields
showing the forecast data, observation data, difference fields, and
some
derived data types as well.

I'd suggest checking your Grid-Stat config file to see if you have the
nc_pairs_flag option enabled:

//
// NetCDF matched pairs output file
//
nc_pairs_flag   = {
   latlon      = TRUE;
   raw         = TRUE;
   diff          = TRUE;
   climo      = FALSE;
   weight    = FALSE;
   nbrhd      = FALSE;
   apply_mask = TRUE;
}

I'd suggest configuring it as listed above.  That'll write out the
forecast, observation, and difference fields separately for each
masking
region you defined.  If you set "apply_mask = FALSE" then you'd get
output
for the full verification domain without your masks applied to it.

Hope that helps get you going.

Unfortunately, while I do have access to theia, I do not have access
to
WCOSS.  But my colleague does.  If you have more questions next week,
I
could ask her to go grab some data.

Thanks,
John Halley Gotway
