You can read this data using Tom's VisAD TextAdapter, as described at:

I highly recommend Ugo's tutorial to learn about such matters, at:

  http://www.geogr.uni-jena.de/~p6taug/visad/tutorial/index.html

Section 4.1 and its P4_01.java code provide an example of what
you want to do. But if you want to use VisAD, its a good idea to
work through the tutorial.

Good luck,
Bill
