A mathematical description of the physics behind Aurora?

[QUOTE="dykuma, post: 6421018, member: 570190"] I should have clarified, I was asking about the colors/wavelengths of light of excited gasses (N2 and O2) as a function of altitude. Lightning at lower altitudes is blue, where light from excited nitrogen is dominate, and I was considering the excitation due to lower and upper atmospheric lightning to be roughly the same as aurora, though obviously both are initiated by very different processes (usually). Anyway, I have a rough understanding of how atoms with electrons level emit light, or how vibrational modes of molecules do the same. My question was more directed at a more statistical approach to figure out the idea altitudes for various emissions. Using your neon sign analogy, if I were to excite a column of air, what I'm looking for it a way to determine what colors are present at a certain altitude for a given molecule. [/QUOTE]
