Investigating Chemical Processes in the MLT Region Using a Model of Wave-Driven Airglow Fluctuations

这个为期三年的奖项是为了继续和扩大有关重力波对小物种密度的影响和相关的中层顶/低层热层（MLT）区域夜光发射的研究。对于给定的平均状态和一组重力波参数，发射波动的特征将取决于发射过程中涉及的化学途径。通过仔细的建模，将使用几种不同的化学途径来研究氧发射波动的特征，这些化学途径已被提出用来解释排放。初步分析表明，不同可能的化学途径在辐射波动方面存在明显差异。通过扩展这些分析，将有可能在每种不同化学途径特有的发射波动中寻找特征。在理论发展之后，将对地基和天基排放数据进行广泛的诊断分析，寻找预测特征，并推断所涉及的化学途径。* * *

9402434 Hickey This three year award is for continuation and expansion of studies related to the effects of gravity waves on the minor species' densities and associated nightglow emissions of the mesopause/lower thermosphere (MLT) region. For a given mean state and set of gravity wave parameters, the characteristics of the emission fluctuations will depend on the chemical pathways involved in the emission process. By careful modeling, the characteristics of the oxygen emission fluctuations using several different chemical pathways that have been proposed to explain the emissions will be investigated. Preliminary analyses have shown that obvious differences exist in the emission fluctuations for the different possible chemical pathways involved. By expanding these analyses, it will be possible to search for signatures in the emission fluctuations that are peculiar to each of the different chemical pathways. The theoretical development will be followed by extensive diagnostic analysis of both ground-based and space-based emission data, searching for the prognostic signatures, and deducing the chemical pathways involved. ***
