I put together some jython code and a formula ("rotateRadar") and they are in 
the attached plugin.
There was a small problem in our underlying radar data that I have fixed so you 
will need to get tonight's nightly build for this to run. Just install the 
plugin (through Tools->Plugin manager -File menu).
The rotateRadar formula prompts the user for an angle  (degrees) and a radar 
field. Select one of the specific elevation fields (e.g, 0.5 degree 
reflectivity) - not the fill volume.
