CEDAR: Study of Mesospheric Airglow and Dynamics: Analysis and Interpretation of Aloha-90 Campaign

高层大气明显偏离辐射平衡，其环流和热结构似乎主要是由于小尺度重力波运动的强迫。虽然大气层的这一区域显示出大量有趣的大气现象，但它是地球大气层中最不为人所知的区域。因此，高层大气和低层热层的化学和动力耦合的详细研究已被确定为NSF CEDAR计划的一个主要组成部分。重力波参数对于了解该区域的动力学是有用的。为了提高我们对重力波和湍流场的认识，需要收集各种雪松仪器，如激光雷达、光学和雷达系统。这样一个集合，包括PIs的气辉光谱仪，参加了CEDAR支持的运动，机载激光雷达和夏威夷气辉观测（ALOHA），该运动于1990年3月和4月成功进行。参与的实验包括Haleaukala天文台的地面气辉成像仪和干涉仪，圣诞岛的SAD和流星雷达，科罗拉多州的Na温度激光雷达和流星雷达，以及NCAR Electra上的气辉光谱仪和Na激光雷达。该提案要求支持分析伊莱克特拉号上搭载的密歇根气辉光谱仪获得的数据，并利用其他仪器获得的额外信息解释气辉结果。

The upper atmosphere depart significantly from radiative equilibrium and have a circulation and thermal structure that appear to be mostly due to forcing by small-scale gravity wave motion. Although this region of the atmosphere exhibits a large number of interesting aeronomical phenomena, it is the least understood region of the earth's atmosphere. Detailed studies of chemical and dynamical coupling in the upper atmosphere and lower thermosphere thus have been identified as one major component of the NSF CEDAR program. Gravity wave parameters are useful for understanding the dynamics in this region. A collection of various CEDAR instruments such as lidar, optical, and radar systems, is required in order to improve our knowledge of gravity waves and turbulence field. Such a collection, including the PIs' airglow spectrometer, participated in a CEDAR supported campaign, Airborne Lidar and Observations of the Hawaiian Airglow (ALOHA), which was successfully conducted in March and April of 1990. The participating experiments included groundbased airglow imagers and interferometers at Haleaukala Observatory, SAD and meteor radars at Christmas Island, a Na temperature lidar and meteor radar in Colorado, and airglow spectrometers onboard the NCAR Electra along with a Na lidar. This proposal requests support to analyze the data obtained by the Michigan airglow spectrometer onboard the Electra and to interpret the airglow results with additional information from those obtained by the other instruments.
