This award will provide logistical support for a period of five years to the NOAA Aeronomy Laboratory to make measurements from McMurdo and Palmer Stations in Antarctica, and to provide some logistical help in Thule, Greenland. Ground-based visible and ultraviolet spectroscopy will be used to measure stratospheric column abundances of ozone (O3), nitrogen di (and tri) oxide (NO2 and NO3), chlorine dioxide (OClO) and bromine monoxide (BrO). The simultaneous measurements of these gases, and their seasonal and diurnal variations, are of particular value in studying the polar ozone holes and the photochemistry which is responsible for the destruction of ozone. This project is important for the study of manmade effects on global change.

该奖项将为NOAA航空实验室提供五年的后勤支持，以从南极洲的McMurdo和Palmer站进行测量，并在Greenland Thule提供一些后勤帮助。 地面可见和紫外光谱将用于测量臭氧（O3），氮DI（和Tri）氧化物（NO2和NO3），二氧化碳（OCLO）（OCLO）和Bromine Onoxide（BRO）的平流层丰度。 这些气体的同时测量以及它们的季节性和昼夜变化在研究极性臭氧孔和负责破坏臭氧的光化学方面具有特别有价值。 该项目对于研究人造对全球变化的影响很重要。
