The absorption of solar ultraviolet radiation in the upper atmosphere results in the ejection of electrons from the atoms and molecules, as does the impact of high energy particles during auroral displays. The ejected electrons collide with other atmospheric molecules and atoms and cause them to emit light, which can then be used as a means of remotely sensing the processes occurring, and also the changes in composition and the temperature of the atmospheric region bombarded. The research to be performed at JPL is of laboratory measurements of the light emission from a beam of atoms or molecules colliding with a beam of electrons. The results will be interpreted at the University of Arizona, and put in a form suitable for the analysis of upper atmospheric optical data to yield parameters of the source region.

高层大气对太阳紫外线辐射的吸收导致原子和分子中电子的喷射，极光显示期间高能粒子的撞击也是如此。 喷射出的电子与其他大气分子和原子碰撞并导致它们发光，然后可以将其用作遥感所发生的过程以及所轰击的大气区域的成分和温度的变化的手段。 喷气推进实验室将进行的研究是对原子束或分子束与电子束碰撞时发出的光进行实验室测量。 结果将在亚利桑那大学进行解释，并采用适合分析高层大气光学数据的形式，以产生源区域的参数。
