Coordinated Imaging and Incoherent Scatter Radar for Sub-Auroral Ionospheric Research

单色成像设备就像电视摄像机，增加了在一个波长的光下成像的能力，比如电离层氧离子重组时发出的630纳米波长的光。然而，与电视摄像机相比，它们对弱光的敏感度要高得多，并且可以将数字形式的图像数据直接输入计算机。将建造一个成像仪，提供整个天空的图像，并配备一套滤镜，以在四种波长中的任何一种进行成像。通过这种方法，可以得到85km和95km高度的Na和O，以及150km和250km高度的N2+和O+等几个水平的排放结构。成像仪将与磨石山的雷达一起用于研究磁暴对电离层的影响。它还将被带到美国、加拿大和海外的其他地区，与雪松协调运动中的其他仪器一起进行观测，例如研究中流层区域（80至100公里高度）的波浪和风。PI和他的同事是该设备的建造以及图像数据处理和结果解释方面的国际专家。

Monochromatic imaging devices are like television cameras, with the capability added to make images in the light of just one wavelength, such as that emitted at 630 nm wavelength when ionospheric oxygen ions recombine. However, they have much greater sensitivity to low light levels than television cameras, and read out the image data in digital form directly into computers. An imager is to be built that provides images of the whole sky and is equipped with a set of filters to image in any one of four wavelengths. In this way the structure of the emissions from several levels such as from Na and O at 85km and 95km altitude, and N2+ and O+ from 150 and 250 km altitude can be made. The imager is to be used in conjunction with the radar at Millstone Hill for study of magnetic storm effects on the ionosphere. It will also be taken to other parts of the USA, Canada and overseas for observations with other instruments in CEDAR coordinated campaigns, such as in studies of the waves and winds in the mesopause region (80 to 100km altitude). The PI and his associates are international experts in construction of this equipment and in image data processing and interpretation of the results.
