American Geophysical Union (AGU) Chapman Conference on Advances in Understanding Alfven Waves in the Sun and the Heliosphere; Berlin, Germany; May 28-June 2, 2023

空间等离子体中的阿尔芬波已经被研究了几十年。它们被记录在行星的磁层中（例如，地球，木星），太阳风，以及太阳大气。尽管这些区域的等离子体性质存在很大差异，但研究的首要主题是波的产生，波的传播和波的耗散，这是任何一种波的三个基本方面。波的第四个方面是它们的应用，无论是对人类还是对科学研究都有直接的好处。这笔赠款资助了一个国际会议，重点是研究阿尔芬波。支持包括学生和早期职业科学家参加和出席会议的旅行。计划出版AGU专著和期刊特刊以传播所提出的结果。查普曼会议将于2023年5月28日至6月2日在德国柏林举行。这次跨学科会议旨在汇集来自不同社区的科学家，审查和讨论空间等离子体中阿尔芬波的研究现状，包括太阳大气层、太阳风、行星磁层和电离层以及实验室等离子体（如果与空间等离子体有关）。此前的两次与波有关的查普曼会议侧重于超低频波（2005年的磁层超低频波，2014年的空间等离子体中的低频波）。第一个重点是地球磁层中的波，第二个是跨学科的，包括太阳大气层和其他行星磁层中的波（例如，该奖项反映了NSF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。

Alfvén waves in space plasmas have been studied for several decades. They have been recorded in the magnetospheres of planets (e.g., Earth, Jupiter), the solar wind, as well as the solar atmosphere. Despite the great differences in the plasma properties of these regions, the overarching themes of research are wave generation, wave propagation, and wave dissipation, which are three fundamental aspects of any kind of waves. A fourth aspect of waves is their application, either with direct benefit to humans or for scientific pursuit. This grant funds support for an international conference focusing on research in Alfven waves. Support includes travel for student and early career scientists to participate and present at the conference. An AGU monograph and a special issue of a journal are planned for disseminating the results presented.The Chapman Conference on Advances in Understanding Alfven Waves in the Sun and the Heliosphere will be held in Berlin, Germany from May 28-June 2, 2023. This interdisciplinary conference aims to bring together scientists from different communities to review and discuss the current state of research on Alfven waves in space plasmas, including the solar atmosphere, the solar wind, planetary magnetospheres and ionospheres, and laboratory plasmas (if relevant to space plasmas). Two prior wave-related Chapman conferences focused on ultra-low frequency waves (Magnetospheric ULF waves in 2005, Low-frequency waves in space plasmas in 2014). While the first one focused on waves in Earth’s magnetosphere, the second one was interdisciplinary, including waves in the solar atmosphere and other planetary magnetospheres (e.g., Jupiter, Mars).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.
