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，旨在翻新和升级Arecibo天文台现有的Fabry-Perot干涉仪（FPI）中的现代工具。由此努力将是带有新硬件和软件的双线成像FPI，具有更高的灵敏度，将是自动化和远程可操作的，并且能够同时测量电子区域和F-Region中性风。升级将使热层中性风和温度在Arecibo天文台的准确性高度进行定期测量。基于地面的FPI构成了风信息的关键来源，活动将确保并提高Arecibo仪器的能力，而Arecibo仪器的能力就位于电动动力学过程的关键位置。具体而言，升级将允许在Arecibo收集了30多年的持续热层气候。自动数据收集将增加风暴时间数据的量，以了解在高磁性活动期间如何修改热层风场。社区基础设施构建和服务是活动的核心。 处理后的数据将轻松地通过现有的空气社区Madrigal数据库提供，并将促进各种高层大气动力学和热力学科学调查。这些研究适合全球气候变化研究的更大背景。 该设施和数据也将用于支持各种教育活动。
