气辉数值研究中使用的大气参考模型是重要的,因为气辉的发射取决于发光物质的数量密度。在本研究中,我们采用二维、非线性、时间相关的数值模型,多重气辉化学动力学(MACD)和OH化学动力学(OHCD),以msse -90、nrlmsse -00和Garcia and Solomon (GS)模式数据作为大气参考模型,研究重力波诱导气辉在中低层热层(MLT)区域OH(8,3)气辉、O2(0,1)大气波段和O(1S)绿线发射的变化。结果表明,OHCD-00产生的OH(8,3)气辉强度变化最大(约34%),其次是OHCD-90(约30%),然后是OHCD(约22%)。对于O(1S)绿线,MACD产生最大的波动引起的变化(~ 33%),其次是MACD-90(~ 28%),然后是MACD-00(~ 26%)。对于O2(0,1)大气波段,MACD产生的波动诱导变化最大(约31%),其次是MACD-90和MACD-00(约29%)。我们的研究说明了一个好的大气参考模型的重要性和必要性,它可以准确地代表大气。
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 (∼34%), followed by the OHCD-90 (∼30%), then by the OHCD (∼22%). For O(1S) greenline, the MACD produces the largest wave-induced variation (∼33%), followed by the MACD-90 (∼28%), then by MACD-00 (∼26%). As for O2(0,1) atmospheric band, the MACD produces the largest wave-induced variation (∼31%), followed by the MACD-90 and MACD-00 (∼29%). Our study illustrates the importance and the need for a good atmospheric reference model that can accurately represent the atmosphere.
