Airglow has been used as an indicator of atmospheric structure and dynamics in the Aeronomy community because it is very sensitive and responsive to changes in the atmosphere. A two-dimensional, time-dependent, nonlinear OH Chemistry Dynamics (OHCD) model and a Multiple Airglow Chemistry Dynamics (MACD) have been used for the investigations of airglow intensity variations in the MLT region observed from the ground. A review of the simulation results from these two models will be provided. The model each consists of an airglow chemistry model and a spectral full-wave model, and it has the capability of turning on or off the spectral full-wave model to study gravity wave-airglow interaction or airglow variations induced by non-wave effects. In this talk we focus on gravity wave-airglow interactions on OH airglow, O2 atmospheric band, and O(1S) greenline. Specifically, results of gravity wave-induced airglow variations, OH exothermic heating rate variation, the intensity-weighted temperature variations, and the phase relationship between airglow and its temperature will be presented.
