The principal objective of this project is to measure UV and visible radiation at the ground in the Arctic and utilize these data to infer column abundances of atmospheric ozone and other trace gases important in the ozone chemistry. This will be accomplished by measuring intensity ratios for wavelength pairs in the Huggins band to determine column ozone content, and visible absorption spectroscopy to derive column abundances of NO2, NO3. Measuring OClO is far more difficult because of its small abundance, but inference of its column abundance may be attempted. However, the emphasis will be on developing the capability and demonstrating the feasibility of measuring NO2, O3 and NO3 column abundances in the Arctic. Thus, the main effort of the research project will be focused on developing the experimental techniques and acquiring the experience required for reliable trace gas measurements as well as on developing the theoretical modeling tools essential for the analysis of the measurements.

该项目的主要目标是测量紫外线和 北极地面的可见光辐射， 用于推断大气臭氧柱丰度和其他 臭氧化学中重要的痕量气体。 这将是 通过测量波长对的强度比来实现 在哈金斯带确定柱臭氧含量， 可见吸收光谱法，以获得柱丰度 NO2、NO3。 测量OClO要困难得多，因为 小丰度，但其柱丰度的推断可能是 企图。 然而，重点将放在发展 能力，并证明测量NO2，O3的可行性 和北极的NO3气柱丰度。 因此， 该研究项目将集中于开发 实验技术和获得所需的经验， 可靠的痕量气体测量以及开发 理论建模工具的分析必不可少的 测量.
