AB: Chemical reactions of the oxygen and hydrogen families control trace species such as mesospheric ozone and emissions by the dominant airglow features. In this study we focus particularly on the chemistry that affects the OH Meinel band emission of the upper mesosphere, which is measured by SABER. We compare model simulations with SABER emission data and address the following topics: the processes that maintain the vertical structure of the volume emission rate, the role of atomic oxygen transport in the structure and variability of emissions, and how tides and other dynamical processes affect the mean height and emission rate.
