This is a 3-year instrumentation project to refurbish and upgrade an existing Fabry-Perot interferometer (FPI) at the Arecibo Observatory into a modern capable facility. Resulting from the effort will be a dual line imaging FPI with new hardware and software that will have greater sensitivity, will be automated and remotely operable, and will be able to simultaneously measure E-region and F-region neutral winds. The upgrade will allow thermospheric neutral winds and temperatures to be measured routinely and continuously with high accuracy at the Arecibo Observatory. Ground-based FPIs constitute a crucial source of wind information and the activity would secure and improve the capability of the Arecibo instrument, which is located at a key location with respect to electrodynamic processes. Specifically, the upgrade will allow for a continuation of an ongoing thermospheric climatology that has been collected at Arecibo for more than 30 years. The automated data collection will increase the amount of storm time data, needed to understand how the thermospheric wind field is modified during periods of high magnetic activity.Community infrastructure building and service is at the heart of the activity. Processed data will be made readily and freely available via the existing aeronomy community Madrigal database and will facilitate a wide range of upper atmosphere dynamics and thermodynamics science investigations. Such studies fit within the larger context of Global Climate Change research. The facility and data will also be used in support of various educational activities.

这是一个为期3年的仪器项目，旨在将阿雷西博天文台现有的法布里-珀罗干涉仪（FPI）改造和升级为现代化的设施。这项工作将产生一个具有新硬件和软件的双线成像FPI，该FPI将具有更高的灵敏度，将是自动化和远程操作的，并且能够同时测量E区和F区的中性风。升级后，阿雷西博天文台将能够对热层中性风和温度进行定期和连续的高精度测量。陆基FPI是风信息的重要来源，该活动将确保并提高位于电动过程关键位置的Arecibo仪器的能力。具体而言，升级将使在阿雷西博收集了30多年的正在进行的热层气候学得以继续。自动化数据收集将增加风暴时间数据的数量，这是了解热层风场在高磁活动期间如何改变所必需的。社区基础设施建设和服务是活动的核心。 处理后的数据将通过现有的高空大气学社区牧歌数据库随时免费提供，并将促进广泛的高层大气动力学和热力学科学研究。这些研究符合全球气候变化研究的大背景。 该设施和数据还将用于支持各种教育活动。
