Using Remote Sensing and In-situ Observations to Advance Numerical MagnetoHydroDynamic (MHD) Simulations of Coronal Mass Ejection Eruptions

太阳爆发耀斑和日冕物质抛射(或称日冕物质抛射)对于空间天气预报至关重要。这一为期三年的项目包括最近的“日地系统可靠集合预报路线图”报告(NITA等人，2018年)中概述的一些新兴研究方向。此外，这项工作将促进发现，同时促进教学、培训和学习。此外，它还将通过网络和伙伴关系加强研究和教育的基础设施。该项目团队设想，很大一部分工作将由加州大学伯克利分校SSL的博士后研究学者进行。首席研究员(PI)和合作者PI有指导和监督学生研究人员的经验，研究地点--加州大学伯克利分校--提供了让高素质的本科生和研究生参与空间物理研究的机会。这项工作的结果将随着PI、Co-Pi和博士后学者将在国内和国际科学会议(包括国家科学基金会的S闪耀研讨会)上、在学术讨论会和研讨会上公布他们的结果，并发表在同行评议的杂志上而广泛传播。这个为期三年的项目将结合数据分析、建模和磁流体动力学(MHD)模拟，以促进我们在日冕物质抛射(CME)爆发过程的第一原理(FP)描述的基础上对日冕物质抛射(CME)的发起和演化进行模拟的数值能力。项目组将通过日冕物质抛射的磁场和等离子体动力学以及喷发过程中喷出物质和周围日冕中等离子体加热的分布和演变，研究日冕与日冕之间的联系。该项目建立在该小组先前调查洲际生态系统内加强组成的全球结构的创新和经证实的基础上，该工作揭示了与洲际生态系统的地球有效性之间耐人寻味但无法解释的统计关系。该项目非常适合NSF的日地研究(STR)计划，因为它将FP CME的启动和演化研究与观测受限的经验日冕加热参数化相结合，以生成可直接与日冕等离子体诊断和CME/ICME场和等离子体结构的远程和现场观测相比较的模拟输出。该项目的研究和EPO议程支持AGS部门在发现、学习、多样性和跨学科研究方面的战略目标。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

Eruptive solar flares and Coronal Mass Ejections (or CMEs) are of critical importance for space weather forecasting. This three-year project encompasses a number of the emerging research directions outlined in the recent "Roadmap for Reliable Ensemble Forecasting of the Sun-Earth System" report (Nita et al., 2018). Additionally, the work will advance discovery, while promoting teaching, training, and learning. Furthermore, it will enhance the infrastructure for research and education through networks and partnerships. The project team envisions that a significant portion of the work will be carried out by a postdoctoral research scholar at the SSL of the University of California at Berkeley. The Principal Investigator (PI) and Co-PI have experience mentoring and supervising student researchers and the location of the research -- the UC-Berkeley -- presents the opportunity to involve highly-qualified undergraduate and graduate students in space physics research. Results from the work will be disseminated broadly as the PI, Co-PI, and postdoctoral scholar will present their results at national and international scientific meetings (including the National Science Foundation (NSF)'s SHINE Workshop), in colloquia and seminars, and publish them in peer-reviewed journals.This three-year project will combine data analysis, modeling, and magnetohydrodynamic (MHD) simulations in order to further our numerical capabilities to model the initiation and evolution of Coronal Mass Ejections (CMEs) on the basis of a first-principles (FP) description of the eruption processes. The project team will examine the corona-to-heliosphere connection of CMEs via their magnetic field and plasma dynamics and the distribution and evolution of plasma heating in the ejecta material and surrounding corona during the eruption process. The project builds upon the innovative and proven foundation of the team's prior work investigating the global structure of enhanced composition within ICMEs, which revealed an intriguing, yet unexplained statistical relationship with the geo-effectiveness of ICMEs. The project is ideally suited for the NSF's Solar-Terrestrial Research (STR) program as it combines the study of FP CME initiation and evolution with observationally-constrained, empirical coronal heating parameterizations in order to generate modeling outputs that can be directly compared to remote and in-situ observations of coronal plasma diagnostics and CME/ICME field and plasma structures. The research and EPO agenda of this project supports the Strategic Goals of the AGS Division in discovery, learning, diversity, and interdisciplinary research.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.
