The Aeronomic Problem of Oxygen Dissociation
ABSTRACT (Received 33 March, 1954) The vertical distribution of molecular oxygen above 100 km, obtained from recent rocket data, cannot be explained by photo-chemical equilibrium. An aeronomic study of departures from photo-equilibrium conditions in the lower thermosphere shows that atmospheric mixing or diffusion must be operative. It is concluded that the process of diffusion contributes increasingly to molecular oxygen concentrations at greater heights. By considering a diffusive equilibrium, it is found that new information can be obtained for various aeronomic processes
