National Ozone Expedition (NOZE) Lidar Observations of PolarStratospheric Cloud, Aerosol, and Ozone Distributions

该项目将使用激光雷达系统继续研究极地平流层云(PSC)和平流层气溶胶在南极洲上空每年春季臭氧消耗中所起的作用。建议者将对1987年8月和9月第二次国家臭氧考察(NOZE-2)中使用的激光雷达进行升级，并在1988年8月和9月继续进行测量。激光雷达在决定何时发射气球方面特别有价值，这是由另一家机构提供的，这将对PSC进行更详细的测量。这项工作还将导致对PSC的患病率和性质进行独立研究。到目前为止关于南极臭氧层空洞的情况是，PSC必须在导致臭氧破坏的化学过程中发挥关键作用，而且为了能够预测，尽可能多地了解所涉及的过程是至关重要的，而且可能会先发制人，在较低纬度发生类似的情况。SRI国际公司在将激光雷达技术应用于环境测量方面处于领先地位。

This project is to continue research using a lidar system on the role that polar stratospheric clouds (PSC's) and stratospheric aerosols play in the annual springtime depletion of ozone over Antarctica. The proposers will upgrade the lidar that was used in the second National Ozone Expedition (NOZE-2) in August and September of 1987 and with it continue to make measurements during August and September of 1988. The lidar is particularly valuable as a aid in deciding when to launch balloons, provided by another institution, that make more detailed measurements of the PSC's. The work will also lead to independent research on the prevalence and nature of the PSC's. A main result of the studies done to date on the Antarctic ozone hole is that the PSC's must play a key role in the chemistry that leads to the destruction of ozone and it is essential that as much as possible learned about the processes involved in order to be able to predict, and possibly forestall, similar occurrences at lower latitudes. SRI International is a leader in the application of lidar technology to environmental measurements.
