项目摘要
Two Doppler lidars, a newly developed iron (Fe) Doppler lidar and an existing sodium (Na) Doppler lidar will be operated simultaneously at Table Mountain near Boulder, CO, to acquire vertical profiles of neutral atmospheric horizontal and vertical winds, temperatures, and Fe and Na densities in the mesosphere and thermosphere to study coupling and transport processes between 80 and 150 km. The thermospheric metal layers themselves involve the coupling between ion and neutral metal layers, and the neutral winds and temperatures derived from these layers are two critical parameters needed for advancing our understanding of the space-atmosphere interaction region. The neutral wind and temperature data in the mesosphere and thermosphere will help validate global models that cover the lower and upper atmosphere (e.g., WACCM and WAM). The simultaneous measurements of Fe and Na layers and their fluxes will provide crucial information on the thermospheric metal layer formation, differential meteoric ablation, and cosmic dust velocity distribution. This work will lead to improvements in quantitative estimates of the cosmic dust input that has implications for a variety of geophysical processes throughout the polar atmosphere and Southern Ocean. Specifically, the dual lidar observations, along with correlative studies and model simulations, will be used to: (1) Characterize the recently discovered thermosphere Fe and Na layers above Table Mountain to determine how frequently they occur, how high they extend, how long they persist, and what mechanisms cause them to form; (2) Characterize neutral winds and temperatures in the 100-150 km region of the thermosphere by using the thermosphere Fe and Na layers as tracers. Explore coupling and transport processes via comparison with the Whole Atmosphere Model (WAM) simulations; and (3) Make simultaneous measurements of wave-induced vertical heat fluxes and the dynamical and chemical fluxes of Fe and Na in the mesopause region (80-105 km) to quantify the differential meteoric ablation of Fe and Na, constrain the various cosmic dust velocity distribution models, help validate the University of Leeds chemical ablation model (CABMOD) and significantly improve estimates of the global influx of cosmic dust. This project will provide research opportunities for a postdoc and a graduate student.
两个多普勒激光雷达,一个新开发的铁多普勒激光雷达和一个现有的钠多普勒激光雷达将在科罗拉多州博尔德附近的桌山同时运行,以获取中间层和热层中性大气水平和垂直风、温度以及铁和钠密度的垂直廓线,研究80至150公里之间的耦合和传输过程。热层金属层本身涉及离子层和中性金属层之间的耦合,从这些层中导出的中性风和温度是推进我们对空间-大气相互作用区域的理解所需的两个关键参数。中间层和热层的中性风和温度数据将有助于验证覆盖低层和高层大气的全球模型(例如,WACCM和WAM)。同时测量的Fe和Na层及其通量将提供重要的信息热层金属层的形成,差分流星消融,和宇宙尘埃的速度分布。这项工作将导致改进对宇宙尘埃输入的定量估计,这对整个极地大气层和南大洋的各种地球物理过程都有影响。具体而言,双激光雷达观测,沿着相关研究和模式模拟,将用于:(1)表征最近发现的桌山上方的热层Fe和Na层,以确定它们出现的频率,它们的高度,它们的持续时间以及它们形成的机制;(2)利用热大气层的Fe和Na层作为示踪剂,确定热大气层100-150公里区域中性风和温度的特征。通过与全大气模式(WAM)模拟的比较探索耦合和传输过程;(3)同时测量中层顶区域的波致垂直热通量和Fe、Na的动力学和化学通量(80-105公里),以量化Fe和Na的差异流星消融,限制各种宇宙尘埃速度分布模型,有助于验证利兹大学化学烧蚀模型(CABMOD),并显着提高对宇宙尘埃全球流入的估计。 这个项目将为博士后和研究生提供研究机会。
