[edit] Whistler as an Impulse response
This was really my personal idea, but people in my research group at Stanford agree with the concept. However, impulse response is generally a term that we apply to linear and time-invariant systems. The magnetosphere is certainly not time-invariant (though it can be quasi-static on short time scales) and it is sometimes (but not always) nonlinear. Also, a sferic is not a perfect impulse; it has most of its energy concentrated in the VLF range, and it's (obviously) a finite-duration signal. But it's still a pretty good approximation to an impulse for VLF measurement purposes.
Here's the point: should we cut out the bit about the whistler being the impulse response of the magnetosphere (with the sferic as the impulse), or should we elaborate on it?
Also, should we move/copy it to the whistler article?
