Simulations of Wave-induced Airglow Intensity Variations of the OH(8,3), O2B1 Atmospheric band, and O1S Greenline Emission

A 2-D, time-dependent, nonlinear Multiple Airglow Chemistry and Dynamics model (MACD) and an OH Chemistry and Dynamics model (OHCD) are used to investigate wave-induced airglow intensity variations of the OH(8,3), O2B1 atmospheric band, and O1S greenline emission in the MLT region. The MACD consists of a spectral full-wave model and an O2B1 and O1S nightglow chemistry model whereas the OHCD consists of the same full-wave model and an OH nightglow chemistry model. Two wave packets of 20 min forcing wave period with a horizontal wavelength of 30 km and 60 km are used to study their effects in the three emissions. The amplitude of the 60 km wave packet reaches a maximum at ~ 119 km and that of the 30-km wave packet reaches a maximum at 104 km. It is found that the 60 km wave packet has a much greater impact on the greenline airglow layer than on the other two airglow layers. We will also show phase differences between any of the two airglow emissions for the two wave packets used to gain a better understanding of how gravity waves affect airglow emissions.
