This award is to organize a two-day community workshop for guiding science investigations on a newly discovered upper atmospheric phenomenon named STEVE (Strong Thermal Emission Velocity Enhancement). STEVE is a confined, mauve colored optical phenomenon in the night-sky below the latitude of the traditional (and well-known) auroral region. Properties and mechanisms driving STEVE remain an exciting and unresolved geospace community challenge. This workshop brings senior and early career scientists together with citizen scientists to share their understandings and plan for future observational and modeling activities to better understand the STEVE phenomenon.In this workshop, observational and theoretical geospace scientists and stakeholders will gather to disseminate STEVE research findings, identify outstanding questions, and formulate future research plans and collaboratory studies. The workshop will have two general foci: (1) serve as a venue for developing observation strategies, experimental campaigns and associated observation modes to fill in both synoptic and event-based data gaps; (2) organize modeling efforts, guided by known characteristics to date, to answer key community questions about STEVE physical morphology and dynamics. A post-workshop white paper organized by the workshop steering committee will efficiently capture community discussions, results, and future plans for advancing geophysical understanding of STEVE. This document can also form inputs to community science working groups that will help incorporate STEVE knowledge into physical understanding of the geospace system. Articles on workshop findings in community journals such as EOS will also maintain analysis and observational momentum.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.

该奖项旨在组织一个为期两天的社区研讨会，指导对新发现的高层大气现象STEVE（强热辐射速度增强）的科学研究。史蒂夫是一种局限的、淡紫色的光学现象，出现在夜空中，位于传统的（众所周知的）极光区纬度以下。驱动STEVE的特性和机制仍然是地球空间界一个令人兴奋且尚未解决的挑战。本次研讨会将资深和早期职业科学家与公民科学家聚集在一起，分享他们对未来观测和建模活动的理解和计划，以更好地了解史蒂夫现象。在本次研讨会上，观测和理论地球空间科学家和利益相关者将聚集在一起，传播史蒂夫的研究成果，确定悬而未决的问题，并制定未来的研究计划和合作研究。研讨会将有两个总体重点：(1)作为制定观测策略、实验活动和相关观测模式的场所，以填补天气和基于事件的数据空白；(2)组织建模工作，以迄今已知的特征为指导，回答有关STEVE物理形态和动力学的关键社区问题。由研讨会指导委员会组织的研讨会后白皮书将有效地捕捉社区讨论、结果和未来计划，以促进对STEVE的地球物理理解。该文件还可以作为社区科学工作组的输入，帮助将STEVE知识纳入对地球空间系统的物理理解。在EOS等社区期刊上发表的关于研讨会发现的文章也将保持分析和观察势头。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
