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.

空间等离子体中的Alfvén波的研究已有几十年的历史。它们被记录在行星(例如地球、木星)的磁层、太阳风以及太阳大气中。尽管这些区域的等离子体性质有很大的差异，但最主要的研究主题是波的产生、波的传播和波的消散，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，要么直接造福人类，要么用于科学研究。这笔赠款用于资助一个以阿尔芬波研究为重点的国际会议。支持包括学生和早期职业科学家参加会议并出席会议的旅行。计划出版一本AGU专著和一份期刊特刊，以传播所提出的结果。查普曼会议关于理解太阳和日光层中的阿尔芬波的进展将于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将来自不同社区的科学家聚集在一起，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、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)。之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年的空间等离子体低频波)。第一个奖项专注于地球磁层中的波，第二个是跨学科的，包括太阳大气和其他行星磁层(如木星、火星)中的波。该奖项反映了美国国家科学基金会的法定任务，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。
