[GEMPAK #RGI-969779]: Gempak Decoders

Hi Flavio, 

I received your file and decoded it and do not see the errors that you report.  
In fact, the file appears to be decoded correctly:

dcgrib2 cosmo.gem < cosmo_met5_00_20140514000

-rw-r--r--   1 mjames ustaff 285395456 2014-06-05 15:33 cosmo.gem

 GRID FILE: cosmo.gem

This seems to be an issue with your environment.  From the log file it appears 
that GEMTBL is not set or found:

[8502] 140603/0000[DC 3] Version 6.6.0
[8502] 140603/0000[NA -1] cntrgrib1.tbl
[8502] 140603/0000[DCGRIB -51] can't open grib tables [NA -51], set GEMTBL


* If you are running dcgrib2 from the command line as user LDM, it's likely 
that the Gemenviron file is not being sourced - you will need to source 
~gempak/NAWIPS/Gemenviron to your shell and run dcgrib2 again.

* If you are running dcgrib2 from an LDM pattern action EXEC, then the command 
should include the option "-e GEMTBL=/home/gempak/NAWIPS/gempak/tables/" as 
mentioned at http://www.unidata.ucar.edu/software/gempak/man/prog/dcgrib2.html

    When using with the LDM, the GEMPAK grib routines must be able
    to access the grib tables located in the gempak distribution.
    This is done through the GEMTBL environmental variable.
    If the the LDM process does not have the GEMTBL variable set,
    then you must use the "-e GEMTBL=path" option.

    The following tables files are expected to be found:
        $GEMTBL/grid/cntrgrib[X].tbl
        $GEMTBL/grid/vcrdgrib[X].tbl
        $GEMTBL/grid/wmogrib[X].tbl
        $GEMTBL/grid/[CENTER]grib[X].tbl
        $GEMTBL/grid/dcgrib.tbl
        $GEMTBL/grid/gribkey.tbl
