[Met_help] [rt.rap.ucar.edu #42940] History for Users guide and mapping question

[RAL HelpDesk {for Paul Oldenburg}]

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

Hi-
The users guide (MetV3.0) lists the columns that are output by MODE.
There is a discrepancy both in the column numbering and the fields that
are in the file (Table 6-3). Column 29 does indeed have curvature but
then 30-32 is supposed to have curvature_x and curvature_y (should be
30-31).

 In my output, there are three fields between the areas and the the
intensities (there should be 4 according to the table: the 3 curvatures
and the complexity). Perhaps complexity has been left out?


Unrelated to the users guide:
I have grib files which have been subsetted from a CONUS-wide domain run
by CAPS for the Hazardous Weather Testbed. I am not too familiar with
grib and its intracacies, so have been converting the grib files to
netcdf. However, my mapping information is not being conveyed properly
to mode. 
Can I use a grib file that contains 30 forecast hours in MODE?
I assume that by doing so, the mapping information will be available.


Thanks.

James,

I will ask the keeper of the MET User's Guide document to fix table 6-
3.  I think the indexing of the fields actually
goes like this:

29     CURVATURE
30-31  CURVATURE_X, _Y
32     COMPLEXITY
33-37  INTENSITY_10, _25, _50, _75, _90

Regarding the GRIB file with multiple forecast times, that should work
fine in MODE.  You can use the "-fcst_lead"
and/or "-fcst_valid" (can't remember if that's exactly correct)
command line options to distinguish between the records
with multiple output times in his file.  For example, if you have a
GRIB file containing forecasts of 2-meter
temperature for 10 forecast lead times, and run it through MODE
requesting "TMP/Z2", MODE will use the first record it
finds matching "TMP/Z2".  If however, you specify a particular lead
and/or valid time, it'll apply that search criteria
to find the record you want.

Please let me know if you have any questions.

Thanks,

Paul
