Rayleigh and Sodium Lidar Studies of the Troposphere, Stratosphere, and Mesosphere at the Amundsen-Scott South Pole Station

本项目将继续在南极运行钠共振激光雷达，以研究从平流层下层到中层顶的大气垂直结构和动力学。在项目的第三年，将增加一个铁共振激光雷达，将动力学和温度结构的测量扩展到100公里的高度。此外，一个气辉成像相机将用于研究水平结构。当与从南极定期飞行的普通气球载无线电探空仪一起使用时，最后的仪器补充将提供从表面到100公里高度的温度结构的广泛数据；极地平流层云的性质，这对臭氧化学很重要；中间层金属层的变异性和出现频率，它们在通信和化学中起作用；大气重力波；以及许多其他现象，其中一些是南极独有的。＊＊＊

Abstract 9616664 Papen This project will continue the operation of a sodium resonance lidar at the South Pole in order to study the vertical structure and dynamics of the atmosphere from the lower stratosphere to the mesopause. During the third year of the project, an iron resonance lidar will be added which will extend the measurements of the dynamics and temperature structure to 100 km altitude. Additionally, an airglow imaging camera will be used to study the horizontal structure. When used in conjunction with the normal balloon-borne radio sondes which are regularly flown from South Pole, the final complement of instruments will provide extensive data on the temperature structure from the surface to 100 km altitude; the nature of the polar stratospheric clouds, which are important to ozone chemistry; the variability and frequency of occurrence of metallic layers in the mesosphere, which play a role in communications as well as chemistry; atmospheric gravity waves; and many other phenomena, some of which are unique to the South Pole. ***
