Hi Bill,
Can you provide us with a sample file? If so, you can put it on ftp:
ftp ftp.cgd.ucar.edu
anonymous
[Use your email address for the password]
cd incoming
put ...
put ...
:
quit
and then email me with the exact filename.
I *think* NCL should be able to handle packed grids, but the main
developer is in a class and I'll have to wait to ask him.
