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
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 990308/0000 0 PRES TMPK
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.
