Hi, Steve,

after I generated the two tables, I decoded the SST grib file into gempak.
Here is what I got from gdinfo
************************************************
 GDFILE   = 99110700.sst_gem
 LSTALL   = YES
 OUTPUT   = T
 GEMPAK-GDINFO>r

 GRID FILE: 99110700.sst_gem                                                    
    

 GRID NAVIGATION: 
     PROJECTION:          CED                 
     GRID SIZE:           73  73
     LL CORNER:             -90.00      0.00
     UR CORNER:              90.00      0.00

 GRID ANALYSIS BLOCK: 
      UNKNOWN ANALYSIS TYPE 

 Number of grids in file:     1

 Maximum number of grids in file:   1500

  NUM       TIME1              TIME2           LEVL1 LEVL2  VCORD PARM
    1     991107/0000                              0         NONE WTMPK       
 Parameters requested: GDFILE,LSTALL,OUTPUT.
*********************************************
The thing I don't understand is that why the coordinate is none instead of 
pres. I used gdinfo to check an old SST gempak file, and I got
*******************************************
 GDFILE   = 99030800.sst_gem
 LSTALL   = YES
 OUTPUT   = T
 GEMPAK-GDINFO>r

 GRID FILE: 99030800.sst_gem

 Parameters requested: GDFILE,LSTALL,OUTPUT.
*****************************************************
You can see the difference in VCORD and PARM.

Also when I decoded the SST grib file, I still had the problem. What I got on
the screen was
********************************************************
tempest:/disk19/shangyao/dindex> /usr/local/nawips-5.4/bin/osf/dcgrib -d 
grib.logSST0700 99110700.sst_gem < /disk12/data/ldm/nps/99110700.SST_grib
 [FL 29] 99110700.sst_gem
 [DM -2]  File 99110700.sst_gem cannot be opened.
 [GD -2]  File 99110700.sst_gem cannot be opened.
 Changing center table to cntrgrib1.tbl
 Changing vertical coord table to vcrdgrib1.tbl
 Changing WMO parameter table to wmogrib3.tbl
 Changing center parameter table to ncepgrib3.tbl
******************************************************
At begining, I did not have any 99110700.sst_gem in my working directory.

Thanks.
