项目摘要

Reconnection of magnetic fields is a fundamental physical process that can accelerate particles and inject energy into systems. In the geospace environment, there are many unanswered questions about how such processes work and impact the space around Earth. This project will investigate the process on the dayside of the Earth in the outer regions of the magnetosphere. Understanding this process is important for predicting and preparing for space weather impacts, particularly to satellites that can be damaged by accelerated particles in the harsh radiation environment in space. The project will support an early career scientist, graduate students, and provide mentorship for undergraduate students.This project will characterize the local time extent of dayside active magnetopause reconnection and investigate what controls dayside reconnection. Specifically, it will address: (1) What is the local time extent of active reconnection?; (2) How is the extent related to local magnetopause current sheet conditions?; and (3) How is the extent related to upstream solar wind conditions? Conjunctions of in-situ and remote-sensing observations will be used. Specifically, NASA’s Time History of Events and Macroscale Interactions during Substorms mission and Magnetospheric Multiscale Mission will be used to identify reconnection events and NSF’s Super Dual Auroral Radar Network will be used to measure the extent of reconnection. Local magnetopause conditions will be obtained from space-ground conjunctions. The solar wind conditions will be provided by spacecraft including NASA's Advanced Composition Explorer, Global Geospace Science Wind satellite, and Geotail, and NOAA's Deep Space Climate Observatory.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.
磁场重联是一个基本的物理过程,可以加速粒子并向系统注入能量。在地球空间环境中,关于这些过程如何工作以及如何影响地球周围的空间,还有许多悬而未决的问题。这个项目将调查地球白天的过程,在磁层的外部区域。了解这一过程对于预测和准备空间天气影响非常重要,特别是对于在太空恶劣辐射环境中可能被加速粒子损坏的卫星。该项目将支持一名早期职业科学家、研究生,并为本科生提供指导。本项目将描述日侧磁层顶活动重联的局部时间范围,并研究控制日侧磁层顶重联的因素。具体来说,它将解决:(1)主动重连的本地时间范围是多少?(2)程度与局部磁层顶流场条件的关系如何?(3)程度与上游太阳风条件的关系如何?将使用现场和遥感观测相结合的方法。具体来说,NASA的亚暴任务和磁层多尺度任务期间的事件和宏观尺度相互作用的时间历史将用于识别重联事件,而NSF的超级双极光雷达网络将用于测量重联的程度。局部磁层顶条件将从空间-地面连接得到。太阳风条件将由航天器提供,包括美国宇航局的先进成分探测器,全球地球空间科学风卫星,Geotail和美国国家海洋和大气管理局的深空气候观测站。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。
