This research program primarily involves laboratory studies related to understanding the metal chemistry of the mesopause region of the atmosphere. Specifically the work will be directed towards specific chemical reactions and theoretical calculations associated with the formation and destruction of the NaO4 molecule. In addition, other studies will investigate heterogeneous chemistry and photosputtering of the alkali metal atoms, oxidation chemistry for Fe and Mg and an expansion of the current model of sodium chemistry in the mesopause region. Understanding of this topic is of great interest in the use of high power lidar systems to study the structure and dynamics of the mesopause and lower thermosphere.

该研究计划主要涉及与了解大气中层顶区域的金属化学相关的实验室研究。 具体来说，这项工作将针对与 NaO4 分子的形成和破坏相关的特定化学反应和理论计算。 此外，其他研究还将研究碱金属原子的异质化学和光溅射、铁和镁的氧化化学以及中层顶区域当前钠化学模型的扩展。 了解这一主题对于使用高功率激光雷达系统研究中层顶和低层热层的结构和动力学具有很大的意义。
