I will let you know how it goes with getting the AWIPS.tbl file to work as a CDL file. Thanks, Brian -----Original Message----- From: Robb Kambic [mailto:address@hidden] Sent: Tuesday, July 08, 2003 11:50 AM To: HOETH, BRIAN R. (JSC-ZS) (LM) Subject: RE: Gribtonc changes Brian, You did it, all the packages are now installed correctly. Yea, give yourself a pat on the back. Now the next thing is to create a cdl file for your data set, taking info from your web page: create new cdl, seems package one is now out of date. % gribtocdl -v 2003070812_A.wmo > eta212.cdl At some point you might want to edit the cdl to make it 100% correct. Now run gribtonc again, remove testETA.nc first or gribtonc will use the old one again. % gribtonc -vl - eta212.cdl testETA.nc < 2003070812_A.wmo Last lines to screen are status: Jul 08 15:02:37 gribtonc[27048]: 179 WMO msgs, 179 GRIBs decoded, 0 written From your web page, it states no data written. So all you had was the template file. Hopefully this time you have 179 written. I know you want to create AWIPS type files, so you have to use the -g AWIPS.tbl for both gribtocdl and gribtonc, ie % gribtocdl -v -g AWIPS.tbl 2003070812_A.wmo > eta212.cdl % gribtonc -vl - -g AWIPS.tbl eta212.cdl testETA.nc < 2003070812_A.wmo I might have some errors in the AWIPS.tbl file, didn't check it 100% I have my fingers crossed, Robb...
