About the only way netCDF could help you with this would be to

 1.  Write a program for the Cray that reads the Cray binary data into
     memory (using your own I/O and knowledge of the data types and
     structures) and then writes it out as a netCDF file (using the
     netCDF library on the Cray).

 2.  FTP the resulting binary netCDF file to the Digital Unix
     workstation.

 3.  Read the resulting netCDF data on the Digital workstation
     using the netCDF library installed on the Digital workstation.

The only kinds of data conversion done in the netCDF library are between
a machine's native representation and the portable netCDF external
representation.  There is no conversion between the native
representation of two different machines in the netCDF library.
