Kim,

The incorrect LEVEL2 definition issue may be a bug that you discovered.  I'm 
waiting to hear back from others about it, and will let you know what I find 
out.

As for the error with GDGRIB, correct me if I'm wrong, but it seems that the 
last grid which was added to your file was 

 GRDNAM   = combinedGGT%PDLY

with 

 GFUNC    = ADD(THTEGGT@0:60%PDLY,GGTpdly@30:60%PDLY)
 GDATTIM  = F000
 GLEVEL   = 0:60
 GVCORD   = PDLY 

however, GDINFO shows combinedGGT saved as

  NUM       TIME1              TIME2           LEVL1 LEVL2  VCORD PARM
  347     080130/0000F000                          0  30     PDLY COMBINEDGGT 


Can you confirm this on your end? (in GDINFO set GLEVEL = all, GVCORD = all, 
GDATTIM = all and GFUNC = COMBINEDGGT)

If I run GDGRIB as you have in your script, with GLEVEL = 30:60, I see an error 
reporting no grid exists (true).  If I change it to GLEVEL = 0:30, I am able to 
write out the grib file as expected. 

I want to make sure that we're on the same page here, as there are a lot of 
steps involved to get to this point, and have COMBINEDGGT written with the 
correct time, v-coord and levels.  If we're good up to this point, then could 
the problem you're experiencing simply be that GLEVEL is defined incorrectly in 
GDGRIB?

Let me know what you find and hopefully I'll have some more info for you about 
the GDDIAG level error.
