Lightning‐induced heating of the nighttime D region leads to the excitation of a number of lines of O, O 2 , N 2 , at intensities of 10–10 9 Rayleighs (R) for vertical observations. For example, the 5577 Å emission from O has intensity ∼60 R lasting for ∼350 ms while the 1st and 2nd positive bands of N 2 are at ∼10 9 R but last only ∼50μs.
