Abstract:

Twenty-four stroke-resolved slit spectra of lightning taken in 1966 are presented, one of which is also the first space-resolved slit spectrum of a return stroke. These split spectra unambiguously show that the lightning return-stroke channel is a strong continuum source and that the continuum observed in the slitless spectra in 1965 is real and not the result of line radiation scattered from natural backgrounds such as clouds, haze, or rain.
