Analysis of Optical Data from Program CEDAR

这项提议是为了进一步发展一个在极光降水事件期间在热层中发生的物理和化学反应的综合模式，并用它们来解释最近和计划中的雪松运动的光谱观测。结果将是关于入射电子和质子的能量分布的信息，以及由于降水而导致的大气成分的变化。拟议的工作可能会大大提高我们利用地面观测推断极光对大气的物理和化学影响的能力，包括加热效应和成分变化。目前需要这种解释能力，这种能力在未来几年将会增加，因为协调极光观测的雪松运动产生了大量的数据集。PI非常有资格执行这项工作，因为他已经开发了目前可用于这类工作的最全面的模型。

This proposal is to further develop a comprehensive model of the physical and chemical reactions occurring in the thermosphere during auroral precipitation events, and to use them to interpret spectrographic observations from recent and planned CEDAR campaigns. The result will be information on the energy distribution of incident electrons and protons, and changes in atmospheric composition as a result of the precipitation. The proposed work is likely to lead to a significant advance in our ability to use ground based observations to infer the physics and chemistry of auroral effects on the atmosphere, including heating effects and composition changes. There is a current need for such an interpretive capability, which will be increasing during the next few years, as the CEDAR campaigns of coordinated auroral observations produce extensive data sets. The PI is highly qualified to perform such work, as he has developed the most comprehensive model currently available for such work.
