Michael,

The BUFR products being sent in NOAAPORT are prepared by JPL.
I added the code to read these products and follow the plotting
that NCEP is doing with the data they have in house. NCEP has access 
to a gridded product which JPL is producing which is what the QSCT 
datatype is referencing (the reading and display of that data
follows from the ggqsrd.f routine (called by ggqsct.f).

Since you are at one of the locations that the NCEP developers
support, you probably have direct access to the gridded product.
