i assume you are using the usual scale_factor and add_offset convention?

Hi,

For what it's worth, recent versions of NCO (http://nco.sf.net)
support interpreting packed data to the following extent:

All arithmetic operators (claim to) support packed data.
This means multiple packed data files can be, e.g., easily averaged.
ncap can read and write packed data, i.e., it will pack it for you.
The read functions support packing into any type, so data packed into

NC_CHAR (8 bits) should work fine. I hope people will exercise the packing/unpacking functionality

and let me know how it works for them.
