A New Atmospheric Ozone Source

臭氧的光化学研究一直是一个重要的 自从意识到保护免受 由高层大气臭氧提供的紫外线辐射 不仅仅是学术上的兴趣 只是从20世纪70年代初开始 公众意识是否已经达到了报纸 经常报道可能的臭氧消耗， 大气层的各个区域。 按与确认 南极臭氧洞和新发表的关于 世界范围内的臭氧减少，需要改善我们的 对所有与臭氧有关的过程的了解， 戏剧性地强调。 重要的是要了解所有 臭氧产生的来源，因为在某种程度上， 可能有一些来源没有包括在模型中， 损失机制可能比以往更加重要 假设。 目前的平流层上部大气模式和 中间层无法预测臭氧浓度， 大如所见。 该项目将通过实验 检验振动的光解离 激发的分子，氧，在解离中产生， 臭氧，可以提供臭氧的自催化源， 高层大气 假设的证实可以解决 当前模型与观测值的差异。

Study of the photochemistry of ozone has been an important subject ever since it was realized that the protection from ultraviolet radiation afforded by ozone in the upper atmosphere is of more than academic interest. Only since the early 1970's has public awareness reached the point where newspapers routinely carry stories about possible ozone depletion in various regions of the atmosphere. With the recognition of the Antarctic ozone hole and the newly published report on significant world wide ozone reduction, the need to improve our understanding of all ozone related processes has been dramatically underscored. It is important to understand all the sources of ozone production, because to the extent that there may be sources that are not included in the models, the loss mechanisms could be even more significant than has been assumed. Current atmospheric models of the upper stratosphere and the mesosphere are not able to predict ozone concentrations as large as are observed. This project will experimentally examine the hypothesis that photodissociation of vibrational excited molecular, oxygen, created in the dissociation of ozone, may provide an auto-catalytic source of ozone in the upper atmosphere. Confirmation of the hypothesis could resolve the current discrepancy of the models with observations.
