[Met_help] [rt.rap.ucar.edu #79008] History for MODE - ERROR : Trouble reading forecast file

Mon Jan 30 10:34:28 MST 2017

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

Hi,

Just started using Met, so I apologize if this is a trivial question.  In
running MODE, I encounter:
ERROR  : Trouble reading forecast file

The forecast file is a standard wrfout, though with all Times in one file.
 (I therefore have level = "(89,*,*)"; in my config file to operate on just
the 89th time, for now.)

Any ideas what could be going wrong?

Thanks,
Ryan

Subject: MODE - ERROR : Trouble reading forecast file
From: Julie Prestopnik
Time: Wed Dec 21 12:08:39 2016

I see that you're encountering a problem with MODE reading your
forecast
file.

MET has the ability to read 3 different flavors of NetCDF...
 - The format used to write intermediate files in MET (i.e. the output
of
pcp_combine)
 - NetCDF files following the Climate Forecast conventions (i.e.
CF-compliant NetCDF)
 - The output of the pinterp or wrf_interp utility

Raw WRF output files are not included in that list.  The challenge is
not
the file format but that the data is still in native model levels and
is
defined on a staggered grid.

You have two options...
 - Post-process using the Unified PostProcessor which creates GRIB
output
files.
 - Post-process using the wrf_interp utility which writes a NetCDF
file
that MET reads.

The downside to wrf_interp is that it does not actually destagger the
grid
and doesn't derive any additional output fields.  Practically speaking
that
means you're limited to the raw WRF output variables, and MET can't
read
winds which use the staggered dimension.

I hope that helps.

Please let me know if post processing the standard wrfout file fixing
the
problem.  However most of our staff will be out of the office for the
next
two weeks, so if this does not fix the problem and/or you encounter
other
difficulties it may not be until January until we are able to respond.

Hi Julie,

Thanks for answering.  I installed the UPP but am now having an issue
with
that, so I'll post to upp-help and hope I catch someone before the
break.

Happy Holidays!

I'm sorry to hear you are having problems with the UPP.  Hopefully,
their
help desk will be able to help soon.  We'll leave this ticket open for
now.   Please let us know once you're able to resolve the problem with
MET,
or if you continue to experience problems with MET.
