A Determination of the Line-width of the λ6300 Line of Oxygen in the Twilight Sky

Abstract

THE red doublet (λ6,300–λ6,363) due to oxygen in the upper atmosphere of the Earth is greatly enhanced in twilight, as was shown by Elvey and Farnsworth1 and others. The present study has been undertaken to determine the temperature of the emitting layer from the contour of the λ6,300 component.
