This is an effort aimed at developing, installing, and operating a modern all-sky imaging instrument to study airglow emissions over a site in northern Italy (an astronomical observatory of the University of Padua). The primary science rationale of doing so is to study Stable Auroral Red (SAR) arcs, Medium Scale Traveling Ionospheric Disturbances (MSTIDs), and gravity-wave signatures in the mesosphere. Specifically, the new all sky camera will provide the first ground-based multi-longitudinal coverage for the SAR arc. In combination with the existing Millstone Hill all sky camera, the new camera will allow the examination of the longitudinal variations of the SAR arc, which is crucial for a better understanding of the SAR phenomenon and its relation to the dynamics of the magnetosphere and the ring current. On the medium scale TIDs, the new data sets will be used to explore the effects on source mechanisms in Europe, where the characteristics of geographic and geomagnetic latitudes, and the orientation of the geomagnetic meridians, are quite different from those found in the North and South American sectors that are the main focus of current on-going studies. Likewise, the orograhic differences between Europe and other continents will manifest into longitudinal variations in mesospheric gravity wave activities. The location of the new instrument in the Dolomite Mountain Range will enable the first study of source processes in Europe.The research is fundamentally international in scope, building on a long-established, strong collaboration between scientists at Boston University and the University of Padua in the area of Planetary Atmospheres. The collaboration will be expanded with this effort to terrestrial atmospheric science, with involvement of a new set of students and research staff members from Boston and Padua. A dense network of GPS receivers and ionosondes, already operational within the field-of-view spanned by the imager, will contribute to the studies via collaborations set up with colleagues in Florence (Italy) and Bath (UK). These will be used, together with satellite over-flights, in multi-diagnostic studies by a multi-national team.

这是一项旨在开发，安装和运营现代化的全天堂成像工具的努力，以研究意大利北部（帕多瓦大学的天文观测站）上的气流排放。这样做的主要科学理由是研究稳定的极光红（SAR）弧，中等规模的离子层障碍（MSTIDS）和中层中的重力波特征。 具体而言，新的All Sky相机将为SAR Arc提供首个基于地面的多态覆盖范围。结合现有的Millstone Hill All Sky相机，新相机将允许检查SAR ARC的纵向变化，这对于更好地理解SARMenon及其与磁层和环电流的动力学的关系至关重要。在中等范围内，新数据集将用于探索对欧洲的来源机制的影响，在欧洲，地理和地磁纬度的特征以及地磁子午线的方向与北美地区和南美部门发现的欧洲的方向是完全不同的。同样，欧洲与其他大陆之间的orr氏质差异将表现为中层重力波活性的纵向变化。新工具在白云岩山脉中的位置将使欧洲的源流程进行首次研究。这项研究在范围内是国际性的，建立在波士顿大学与行星氛围领域的科学家与帕多瓦大学的科学家之间建立的悠久，强大的合作。这项合作将通过这项努力扩展到地面大气科学，并参与了来自波士顿和帕多瓦的新学生和研究人员。图像师跨越的视野中已经运行的GPS接收器和Ionosondes的密集网络将通过与佛罗伦萨（意大利）和巴斯（英国）的同事建立的合作来为研究做出贡献。这些将在跨国团队的多诊断研究中与卫星过射线一起使用。
