[GEMPAK #CVB-214443]: GEMPAK Question



Hi Mike,

With GLEVEL=all and GVCORD=all in GDINFO you can view the grids you wish to 
plot:

GEMPAK-GDINFO>l
 GDFILE   = $MODEL/ruc/2012050117_ruc236.gem
 LSTALL   = YES
 OUTPUT   = T
 GDATTIM  = f001
 GLEVEL   = all
 GVCORD   = all
 GFUNC    = HLCY
GEMPAK-GDINFO>r

 GRID FILE: /data/ldm/gempak/model/ruc/2012050117_ruc236.gem                    
                                
...

  NUM       TIME1              TIME2           LEVL1 LEVL2  VCORD PARM
  184     120501/1700F001                       3000  0      HGHT HLCY        
 Parameters requested: GDFILE,LSTALL,OUTPUT,GDATTIM,GLEVEL,GVCORD,GFUNC.
 GEMPAK-GDINFO>


then in GDCNTR, specify GVCORD=hght and GLEVEL=3000:0

GEMPAK-GDCNTR>l
 GDATTIM  = f001
 GLEVEL   = 3000:0
 GVCORD   = hght
 GFUNC    = HLCY
 GDFILE   = $MODEL/ruc/2012050117_ruc236.gem
 CINT     = 0
 LINE     = 3
 MAP      = 1
 MSCALE   = 0
 TITLE    = 1
 DEVICE   = gif|grid.gif
 SATFIL   =  
 RADFIL   =  
 IMCBAR   =  
 PROJ     = mer
 GAREA    = us
 IJSKIP   =  
 CLEAR    = YES
 PANEL    = 0
 TEXT     = 1
 SCALE    = 999
 LATLON   = 0
 HILO     =  
 HLSYM    =  
 CLRBAR   =  
 CONTUR   = 0
 SKIP     = 0
 FINT     = 0
 FLINE    = 10-20
 CTYPE    = C
 LUTFIL   =  
 STNPLT   =  
 GEMPAK-GDCNTR>r

...


the result of this is here:

Hopefully that will get you where you need to go.  Let me know if you have any 
followup questions.
