Neil and Patrick, copied you both on this since you both brought this up at the 
same time.

I am finding it difficult to decode all of the NAVGEM grids.  For example, the 
ground temp and heat flux are decoding correctly after creating the file 
fnocgrib3.tbl and adding entries, but dew-point depression entry, which exists 
in wmogrib3.tbl, is not being decoded.  it may be an issue with the vertical 
coordinates.  

dcgrib was able to decode dewpoint depression from NOGAPS but the parm and 
vcord field in the GEMPAK grid file is blank.  an attempt to decode NAVGEM with 
dcgrib (rather than dcgrib2) failed due to the grid being too large. 

so, lots of problems, but we are getting there.

my fnocgrib2.tbl file is
