Abstract:

The atmospheric attenuation of solar extreme ultraviolet radiation in early morning, June 1962, and late afternoon, October 1962, has been measured. The derived atmospheric composition change in the 170- to 210-km region is interpreted mainly as a diurnal effect. The molecular nitrogen concentration is seen to change but little, while the molecular oxygen concentration decreases by about twenty per cent and the atomic oxygen concentration increases by a factor of about 2 in the afternoon.
