Abstract

The conditions for the feasibility of the daytime photochemical equilibrium approximation of the odd oxygen (O_x) and hydrogen (HO_x) families at altitudes of 50-80 km has been investigated with the use of analytical analysis and a onedimensional model. We proposed the criteria of their equilibrium. It’s shown that when the criterion is limited to 0.1, the difference between the true values of the concentrations of O_x and HO_x and their local equilibrium values is approximately 10%. In this case, one can consider their concentrations to be in an equilibrium and use corresponding algebraic equations in different practical applications.
