Abstract

This paper proposes to remotely sense the translational temperature and the densities of important nocturnal radiators, viz., nitric oxide, carbon dioxide, and atomic oxygen, as functions of altitude in the quiescent nighttime terrestrial thermosphere. The densities of the excited states as functions of altitude are obtained by inverting the measured infrared limb emissions from nitric oxide near 5.3 micrometers , from carbon dioxide near 15 micrometers , and the fine structure lines of atomic oxygen at 63.2 micrometers and 145.5 micrometers . A knowledge of the excitation mechanisms then permits the calculation of the ground states densities.
