This Distributed Arrays of Small Instruments (DASI) project will support observations of the middle atmosphere. This collaboration between academic institutions and a private company will deploy instruments across the Southwestern US. These instruments will be used to measure the dynamics of a complex region of the middle atmosphere where the thermosphere and ionosphere are coupled to each other and to the neutral atmosphere. The data will ultimately help inform our understanding of the space weather events in the atmosphere and inform improvements to global whole atmosphere models. The project leverages a previous NSF-supported effort which successfully placed instruments at high schools across the nation. This project includes planned public seminars and supports undergraduate students.The purpose of this project is to investigate thermosphere-ionosphere coupling by deploying an array of Fabry-Perot interferometers (FPIs) and all-sky cameras across the Southwestern U.S to enable investigations of plasma-neutral dynamics caused both by lower atmospheric and magnetospheric forcing across a range of spatial and temporal scales in the mid-latitude region. Ten OI 557.7nm airglow imagers will form a contiguous field of view spanning 15-20 degrees in latitude/longitude and three FPIs with OI 630.0nm and 557.7nm capabilities. This augments an existing network of 630.0nm imagers that covers some portion of the US and Mexico. Data will be made publicly available through several websites and the NSF funded Madrigal database. Software products will be made available through GitHub.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个分布的小型乐器（DASI）项目将支持中间气氛的观察。学术机构与私人公司之间的这种合作将在美国西南部部署。这些仪器将用于测量中间气氛的复杂区域的动力学，其中热层和电离层相互耦合并与中性气氛耦合。这些数据最终将有助于我们了解大气中的太空天气事件，并为全球整个大气模型的改进提供信息。该项目利用了以前的NSF支持的努力，该努力成功地在全国高中放置了乐器。该项目包括计划的公开研讨会和支持本科生。该项目的目的是通过部署一系列Fabry-perot干涉仪（FPI）（FPI）和全美摄像机来调查热层 - 离子层耦合，以使美国西南部跨越较低的大气层跨越大气的范围，以促进跨度的型号，以促进大气层的范围。中纬度区域。 10 OI 557.7nm气流成像器将形成一个连续的视野，该视图范围为15-20度，纬度/经度和3个FPI，具有OI 630.0nm和557.7nm的功能。这增加了现有的630.0nm成像仪的网络，该网络涵盖了美国和墨西哥的一部分。数据将通过多个网站和NSF资助的Madrigal数据库公开提供。软件产品将通过GitHub提供。该奖项反映了NSF的法定任务，并被认为是使用基金会的知识分子优点和更广泛影响评论标准的评估值得支持的。
