Note that absolute scale doesn't affect render time.

With a density distribution like that, you'll probably be able to reduce 
your render time by clipping the atmosphere at 36 km or even less 
without any noticeable impact (except for a good deal of render speedup 
:-)).

Uh... given the scales you are using, are you sure you need the 
isosurfaces? I guess a bump map should do the job just as well.

Heh, yeah. I know that feeling :-)
