The goal of this project is to study a broad set of upper atmospheric science topics that are all manifestations of highly coupled systems within and connected to the Ionosphere-Thermosphere-Mesosphere (ITM) regions. The contributions to these studies arise from in-house development and deployment of eight low-light-level all-sky-imagers (ASIs). The project has eight areas of activity: (a) the global magnetosphere-ionosphere interactions that create stable auroral red (SAR) arcs, (b) the electrodynamical-ITM processes that create Medium Scale Traveling Ionospheric Disturbances (MSTIDs), (c) the geomagnetic conjugate point controlled aspects of the severe ionospheric irregularities known as equatorial spread-F (ESF), (d) the day-to-day variability of the ionosphere during periods of extended solar and geomagnetic quiescence, (e) dynamical processes in the Mesosphere, (f) experiments of opportunity, (g) comparative aeronomy, and (h) running the CEDAR optical calibration lab. Of particular focus is determining if symmetries or asymmetries exist with longitude and/or hemisphere for the features observed. These include how the tilted geomagnetic dipole creates a mix of processes controlled by geographic latitude (e.g., solar production) versus geomagnetic latitude (e.g., magnetospheric input) within and between the hemispheres.

该项目的目的是研究一系列大气上的科学主题，这些主题都是高度耦合系统的表现，并连接到电离层 - 热球 - 层（ITM）区域。 对这些研究的贡献是由内部开发和部署八个低光级别的全套成像者（ASIS）。 The project has eight areas of activity: (a) the global magnetosphere-ionosphere interactions that create stable auroral red (SAR) arcs, (b) the electrodynamical-ITM processes that create Medium Scale Traveling Ionospheric Disturbances (MSTIDs), (c) the geomagnetic conjugate point controlled aspects of the severe ionospheric irregularities known as equatorial spread-F (ESF), (d) the在延长的太阳能和地磁静止期内电离层的日常变异性，（e）中层中的动力学过程，（f）机会的实验，（g）比较气压，以及（h）运行雪松光学校准实验室。 特别的焦点是确定对所观察到的特征的经度和/或半球是否存在对称性或不对称性。 其中包括倾斜的地磁偶极子如何创建由地理纬度（例如太阳能生产）与半球之间和半球之间的地磁纬度（例如，磁层输入）控制的过程的混合。
