Abstract
The atmospheric reference model utilized in an airglow numerical study is important since airglow emissions depend on the number density of the light-emitting species. In this study, we employ 2-dimensional, nonlinear, time-dependent numerical models, Multiple Airglow Chemistry Dynamics (MACD) and OH Chemistry Dynamics (OHCD), that use the MSISE-90, NRLMSISE-00, and Garcia and Solomon (GS) model data as atmospheric reference models, to investigate gravity wave-induced airglow variations for the OH(8,3) airglow, O2(0,1) atmospheric band, and O(1S) greenline emissions in the Mesosphere and Lower Thermosphere (MLT) region. Our results show that the OHCD-00 produces the largest wave-induced OH(8,3) airglow intensity variation (â¼34%), followed by the OHCD-90 (â¼30%), then by the OHCD (â¼22%). For O(1S) greenline, the MACD produces the largest wave-induced variation (â¼33%), followed by the MACD-90 (â¼28%), then by MACD-00 (â¼26%). As for O2(0,1) atmospheric band, the MACD produces the largest wave-induced variation (â¼31%), followed by the MACD-90 and MACD-00 (â¼29%). Our study illustrates the importance and the need for a good atmospheric reference model that can accurately represent the atmosphere.
