Abstract

THE light of the night sky has excited increased attention since the end of the War ; from the practically minded student of rockets and from astronomers, as well as from students of the upper atmosphere. The astronomer is particularly interested because of the effect of this radiation on his observations. To the student of the upper atmosphere, this radiation has held out a promise of information concerning the composition of the upper air, as well as concerning fundamental processes there. Because of the difficult problem presented by spectroscopy of the light of the night sky, there are still many unidentified radiations in its spectrum, as well as inadequately studied regions. In every review of the contributions of spectroscopy to the study of the upper atmosphere, attention is directed to the desirability of further laboratory investigations of the spectra of O2 and N2, nd the desirability of obtaining emission spectra of ozone and the oxides of nitrogen. It has been suggested that a search along these lines may yield a satisfactory identification of the strong ultra-violet band at ?3556 A.
