I wrote the netCDF import module for VisAD.

The netCDF import module doesn't "understand" packed data at this time
(i.e. it doesn't use the netCDF variable attributes "scale_factor" and
"add_offset").  I intend to add that capbility, however, and your need
will make it sooner rather than later.

What's your time-frame?
