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

这笔赠款将继续支持建设， 最终实现对数据的操作和分析， 南极站的通道激光雷达（光雷达）。 主要 观测能力是： 1. 极地平流层云的完全特性 (PSC整个南极的冬天和春天。 这是 对理解平流层臭氧层有重要意义 洞 2. 使用拉曼测量2至70 km的温度分布 和Rayleigh技术。 3. 南极期间极地中层云的观测 夏天 4. 钠层结构和动力学的测量 在中层顶附近（约90公里高度） 该系统将是一个灵活的通用激光雷达系统， 将能够解决一些重要和紧迫的问题， 与全球变化有关的科学问题。

This grant will continue to support the construction, and eventually the operation and analysis of data, of a powerful multi- channel lidar (light radar) at South Pole Station. The main observational capabilities are: 1. Complete characterization of polar stratospheric clouds (PSC's) throughout the Antarctic winter and spring. This is of great importance in understanding the stratospheric ozone hole. 2. Measure the temperature profile from 2 to 70 km using Raman and Rayleigh techniques. 3. Observation of polar mesospheric clouds during the Antarctic summer. 4. Measurement of the structure and dynamics of the sodium layer near the mesopause region. (about 90 km altitude) The system will be a flexible, general purpose lidar system which will be able to address a number of important and pressing scientific issues related to global change.
