This collaborative project, involving Dartmouth College, the University of Alaska Fairbanks, and SRI, will explore and develop a new data infrastructure through the system-science use of a Swarm-over-Poker 2023 auroral observational campaign. The team will create new and powerful combined data products from this heterogeneous, distributed, multipoint data set and develop a data-sharing platform to share the derived heterogeneous data products and algorithms with the community. These data are interwoven into new, featurized data products and maps for both ionospheric model ingestion and ML studies. These products and tools will enable studies addressing science questions such as how and to what extent the auroral environment context (activity level, local time, latitude) controls the specifics of pre-midnight arc-scale auroral activity and coupling. This is timely as our community moves toward true system-science efforts that require a diversity of data to greatly advance our understanding of auroral generation and electrodynamics. The novelty of this project is that it will demonstrate the design of a research infrastructure for sharing and archiving derived data products from heterogeneous sources to enable new science for cross-scale cross-region coupling auroral studies. Graduate and undergraduate students will be supported by this project. The students exposed to this project will learn to work with heterogeneous and “multifaceted” CEDAR system science, interweaving multiply-distributed data with featurization tools, and with modelling, as needed for cross-scale cross-region coupling auroral studies. The project will host a series of virtual community discussions to engage with the broader geospace community.Swarm-over-Poker 2023 provided the opportunity to collect in situ ionospheric current and flow data from the ESA Swarm spacecraft, during nightly conjunctions with Poker Flat Research Range (PFRR), Alaska, from mid-February through the end of March 2023. The PFRR data include filtered auroral imagery, Poker Flat Incoherent Scatter Radar (PFISR) radar data, ground magnetometry, and additional instrumentation. The Swarm in situ data include thermal ion plasma flow data and field-aligned current data. From this heterogeneous, distributed, multipoint data set, the team will create new and powerful data products to address auroral system science by data-driving ionospheric models. The three science objectives are (1) an auroral system-science study of 2- way arc-scale vs regional-scale coupling for nightside auroral arcs using the winter 2023 Swarm-over-Poker campaign dataset. (2) Generation of tools for, and the data products of, ionospheric model-absorbable imagery-derived and imagery-guided heterogeneous data products for this campaign, and for shared public use. (3) Using this CEDAR-science driven study as a testbed for designing a new data infrastructure for using and sharing heterogeneously-derived CEDAR-science data products. Specific science questions to be addressed are (1) How, and how much, does the regional auroral environment constrain the details of specific arc-scale features? (2) What is the effect on the regional auroral environment, from arc-scale event signatures?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.

这个合作项目涉及达特茅斯学院，阿拉斯加费尔班克斯大学和SRI，将通过系统科学的使用2023 Auroral观察活动来探索和开发新的数据基础架构。该团队将从这个异质，分布式，多点数据集中创建新的和强大的组合数据产品，并开发一个数据共享平台，以与社区共享派生的异质数据产品和算法。这些数据与电离层模型摄入和ML研究的新型数据产品和地图交织在一起。这些产品和工具将启用解决科学问题的研究，例如如何以及在何种程度上（活动水平，本地时间，纬度）控制午夜前弧尺度的极光活动和耦合的细节。这是及时的，因为我们的社区朝着真正的系统科学努力迈进，需要多种数据来促进我们对极光产生和电动力学的理解。该项目的新颖性是，它将展示从异构来源共享和存档派生的数据产品的研究基础架构的设计，以使新科学能够用于跨尺度跨区域耦合的极光研究。该项目将为研究生和本科生提供支持。接触该项目的学生将学习与异构和“多方面”的雪松系统科学合作，将多个分布的数据与特征工具交织在一起，并根据跨尺度跨区域耦合极光研究所需的建模。该项目将举办一系列虚拟社区讨论，以与更广泛的地形社区进行互动。扑克销售者2023在与扑克平面研究范围（PFRR）（PFRR）的夜间连接期间，从阿拉斯加（PFRR）（Alaska）（FFRR）（来自阿拉斯加）（PFRR）（从3月中旬到3月末期）收集了来自ESA Swarm spacecraft的原位离子当前和流量数据。不一致的散射雷达（PFISR）雷达数据，地面磁力测定法和其他仪器。群原位数据包括热离子等离子体流量数据和现场对准电流数据。从这个异质，分布式的多点数据集中，团队将创建新的功能强大的数据产品，以通过数据驱动电离层模型来解决极光系统科学。这三个科学目标是（1）使用2023年冬季2023 Seak-Over-Over-Over-Over-Over-Over-Over-Opker活动数据集的2向弧尺度与区域尺度耦合进行的Auroral System-Science研究。 （2）生成Ionosphere可吸收图像衍生图像和图像引导的异质数据产品的工具和数据产品的生成，并用于共享公众使用。 （3）使用此雪松科学驱动的研究作为测试床，用于设计新的数据基础架构，用于使用和共享异体衍生的雪松科学数据产品。要解决的特定科学问题是（1）区域极光环境如何以及多少限制特定弧规特征的细节？ （2）来自ARC级事件签名对区域极光环境的影响是什么？该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响审查标准来通过评估来诚实地获得支持。
