[GEMPAK #NKM-848711]: decoding NCWF BUFR data?

Chris,
I provide decoder actions for the AWC GRIB format data on NOAAPORT.
See $NAWIPS/ldm/etc/templates/pqact.gempak_decoders.in such as:

# 
# Aviation grids
HDS     ^[YZ]..... KKCI.*/mAWC_NCWD
        PIPE    decoders/dcgrib2 -d data/gempak/logs/dcgrib2_AWC_NCWD.log
                -e GEMTBL=@GEMTBL@
                data/gempak/model/awc/YYYYMMDD_ncwd.gem
#
HDS     ^[YZ]..... KKCI.*/mAWC_CIP
        PIPE    decoders/dcgrib2 -d data/gempak/logs/dcgrib2_AWC_CIP.log
                -e GEMTBL=@GEMTBL@
                data/gempak/model/awc/YYYYMMDD_cip.gem
#  
HDS     ^[YZ]..... KKCI.*/RUC2
        PIPE    decoders/dcgrib2 -d data/gempak/logs/dcgrib2_AWC_TURB.log
                -e GEMTBL=@GEMTBL@
                data/gempak/model/awc/YYYYMMDD_turb.gem


For what its worth, cwordsh is available in the current
binary distributions, so you could grab that if you wanted to play
with your grads program, but I can't help you on that end.

For the GRIB data, they decode into:
 GRID FILE: /data/ldm/gempak/model/awc/20070823_ncwd.gem                        
                                

 GRID NAVIGATION: 
     PROJECTION:          CED                 
     GRID SIZE:         1830 918
     LL CORNER:              20.02    230.02
     UR CORNER:              53.00    300.00

Thats 1,679,940 points- which you'll note is the size I defined in 5.9.4:
http://www.unidata.ucar.edu/software/gempak/GEMPAK5.10/whats_new.html#5.9.4

Displaying the ncwd in GDPLOT2 as an example

IJSKIP=y
GDPFUN=cwdi
TYPE=z   (just fill the grid boxes)
FINT     = 1;2;3;4;5
FLINE    = 0;30;23;18;15;12;7

I didn't define a datatype.tbl alias, but can add that as well.
