Jamie,

GEMPAK is capable of performing objective analysis on surface data as
well as the Laplacian operator for scalar values of gridded data.

GEMPAK provides decoders for surface data, however, since your data has been
archives on CDROM, it is probably not is surface airways transmission format
(which is a good thing, since stations tend to move over the years,
and there is no location information in SAO observations).

So, you will likely have to create a program to read the data from
your CDROM and place into either a Gempak file, or a file that
Gempak can read (such as using the SFEDIT program in Gempak).

If you are not familiar with GEMPAK, you should probably consult with 
Mike Trexler or Darrel Ensley who may be able to help you find
out how to access the software there.
