Robert,

Make sure your script sources Gemenviron, since dcgrib will need
the $GEMTBL directory defined to find the grid tables - 
otherwise you need to use the -g flag because your cron environment
will not have those environmental variables set.
You can add the -d logfile logging if you need to find out
why the output file isn't being created.
