Solar System Laboratory Aeronomy by Electron Impact with Emphasis on Terrestrial Processes

为了了解太阳能转移到地球大气层和大气层内的方式的细节，必须很好地了解存在于大气层每一层的原子和分子的各种状态的基本性质。还必须开发手段，准确校准直接在大气层中测量能量的仪器。该计划将实验室测量与原子和分子物种的高级模型相结合，为推进高层大气过程的研究提供基础数据。详细的模式将被用来模拟激发的夜间或白天的高层大气，并特别注意能量收支。同时，对交叉光束碰撞过程中发射的光的实验室测量将提供大波长区域的校准光谱，为模拟提供主要参考数据集。将对物种N2、02、NiI、OI、HI、NO和Ari进行电子碰撞研究，并将通过模型分析获得与能量相关的碰撞强度，以便建立能够在广泛相关条件下产生结果的碰撞模型。将研究氢排放，因为它可以为航天和实验室仪器提供准确的校准。还将包括解离和预解离产额的测定，绝对跃迁概率表，以及选定物种的高分辨率吸收特性。

In order to understand the details of the way solar energy is transferred to and within the earth's atmosphere it is essential to have a good understanding of the fundamental properties of the various states of the atoms and molecules that exist at each level of the atmosphere. It is also important to develop means to accurately calibrate the instruments that measure the energetics directly in the atmosphere. This program combines laboratory measurements with advanced models of atomic and molecular species to provide basic data to advance research in upper atmospheric processes. Detailed models will be used to simulate the excited night or day upper atmosphere, with particular attention paid to the energy budget. Concurrently, laboratory measurements of the light emitted in a crossed beam collision processes will provide calibrated spectra over a large wavelength region to provide a primary reference data set for the simulations. Electron impact studies of the species N2, 02, NI, OI, HI, NO and ArI will be performed, and energy dependent collision strengths will be obtained through model analysis to allow the construction of collision models capable of producing results for a broad range of relevant conditions. H2 emission will be studied because it can provide accurate calibration of spaceflight and laboratory instrumentation. Also included will be the determination of dissociation and predissociation yields, absolute transition probability tables, and high resolution absorption properties for selected species.
