The PI will make modifications to his field-proven instrumentation and participate in a summer campaign in 1996. The spectrometer used in the 1995 campaign will have improved sensitivity, allowing definitive measurements of ratios between the neutral N2 and the ionized N2+ bands. This improved sensitivity will be facilitated by using a higher gain image intensifier system, which will "see" the night sky background. The PI will continue using the spectrometer with vertical grating rulings to obtain spectrograms, which are spatially resolved in the vertical direction, providing height resolved spectra. The spectrometer will also be used in a special mode to obtain a coarse resolution spectra of other commonly observed optical emission phenomena; the elves.***

PI将对其经过实地验证的仪器进行修改，并参加1996年的夏季活动。 1995年活动中使用的光谱仪将提高灵敏度，从而能够对中性N2和电离N2+谱带之间的比率进行明确的测量。 通过使用更高增益的图像增强器系统，将有助于提高灵敏度，该系统将“看到”夜空背景。 PI将继续使用具有垂直光栅划线的光谱仪获得光谱图，光谱图在垂直方向上进行空间分辨，提供高度分辨光谱。 光谱仪也将在一个特殊的模式下使用，以获得其他常见的光学发射现象的粗分辨率光谱;精灵。
