This award provides the funds to continue flying balloon borne instruments from McMurdo, Antarctica to measure stratospheric ozone and polar stratospheric cloud particles. The annual Antarctic ozone hole remains the most impressive example of how mankind has altered the global atmosphere with pollutants, in this case chlorofluorocarbons. Ozone is the Earth's only protection from the solar ultraviolet radiation (UV-B) that is capable of destroying living matter. The actual causes and mechanisms of the formation ozone hole appear to be fairly well understood; however, continued monitoring of the state of the stratosphere will allow comparisons of the model predictions with actual events in the stratosphere. On an issue of such great importance as the exposure of the surface of the Earth to harmful solar ultraviolet radiation, it is important to keep track of what is happening both to gain improved scientific understanding and as a matter of public policy.This project is jointly funded by the Office of Polar Programs and the Division of Atmospheric Sciences.

这项奖励提供了继续在南极洲麦克默多飞行气球携带的仪器以测量平流层臭氧和极地平流层云粒子的资金。一年一度的南极臭氧层空洞仍然是人类如何用污染物改变全球大气的最令人印象深刻的例子，在这种情况下，污染物就是氯氟烃。臭氧是地球对太阳紫外线辐射(UV-B)的唯一保护，这种辐射能够摧毁生物。臭氧层空洞形成的实际原因和机制似乎相当清楚；然而，继续监测平流层的状态将使我们能够将模型预测与平流层实际事件进行比较。在地球表面暴露于有害的太阳紫外线辐射这样一个非常重要的问题上，跟踪正在发生的事情是重要的，这既是为了增进科学了解，也是作为公共政策问题。该项目由极地方案办公室和大气科学部联合资助。
