Abstract

Daytime composition measurements in the thermosphere from Atmosphere Explorer-C have been analyzed by use of a theory of the ion chemistry. Predicted and measured N//2** plus densities have been compared in order to infer global variations of the solar ionizing flux. Results indicate that the solar flux of H. E. Hinteregger measured on Atmosphere Explorer-C provides an adequate basis for the calculation of solar ultraviolet photo-ionization rates. The role of metastable species is examined, and theoretical O** plus (**2D) densities are presented.
