This would probably be your best bet.  I'd create a
SigmetRadarDataSource that handles that format.  You might
be able to leverage some of the other classes in that package.

The NetcdfSweepfileAdapter is that actual data munger that
NetcdfRadarDataSource uses.  An example CDL is attached.
This is a format used by NCAR for their SPOL radar.

Good luck!
