Abstract

In this paper, the photochemical equilibrium of the odd oxygen and hydrogen families at altitudes of 50-80 km has been investigated via a three-dimensional chemistry-transport model. It is shown that there are wide enough ranges of latitudes, altitudes, and local times when the true concentration value of these families is in the ten percent vicinity of their instantaneous equilibrium values. In this case, the concentrations of these families can be considered to be in equilibrium and appropriate algebraic equations can be used to retrieve poorly measured minor mesospheric constituents, to validate measurement data, or to refine photochemical reaction constants.
