20001228: GEMPAK trajectories

Patrick,

The sfmap output below says that there is no data in the file.

It could be that create_forward.gem is not suceeding if file naming 
isn't correct, or if the packing file isn't found etc.
You will see that the create_forw.gem runs:
trajectory_gem $MAX $LAT $LON $TITLE $GEMTBL/traj.pack forw_${MODEL}.gem $MODEL

You might want to echo out those values and make sure that the program
is finding the input data as well as the packing file etc.
