Abstract
Visible spectra of solar radiation were recorded during sunset. With the development of twilight, there was an expected decrease in the blue-to-red ratio; but directly upon setting of the sun there was a sharp rise in this ratio (due to the predominance of skylight) which attenuated rapidly to follow the pattern that it had previously taken.This publication has 6 references indexed in Scilit:
