Abstract

Determination of atmospheric temperatures from the auroral spectrum is based on measurements of: a) the thermal Doppler broadening of emission lines, and b) the rotational energy distribution of molecules, affecting the intensity distribution within a molecular emission band. Both methods implicitly assume that the excited atoms and molecules from which the radiation emerges are in thermal equilibrium with the surrounding atmosphere, or that the relation between the energies of the excited atoms and molecules can be unambiguously related to the atmospheric temperature.
