AGU Chapman Conference on the Causes and Consequences of the Extended Solar Minimum Between Solar Cycles 23 and 24 (4CESM); Telluride, Colorado; Summer 2012

该委员会将在美国地球物理学联合会的主持下组织一次社区讲习班，称为“关于延长的太阳活动极小期的原因和后果的查普曼会议”。“4CESM”会议将于2012年夏季举行，为期5天，将使太阳和空间物理学界能够就测量、理论和数值建模方面的最新进展进行跨学科的信息和想法交流。“4CESM”会议将为跨学科科学家提供一个论坛，讨论他们对太阳活动周期23和24之间太阳极端最小活动的理解现状，以及这种最小活动对地球的潜在影响。这个不寻常的太阳极小期提供了一个独特的机会来评估一个非常安静的太阳和相对缺乏太阳影响的地球高层大气的性质和结构。太阳物理学面临的首要挑战是解释为什么会发生这种最小值，确定它实际上有多不寻常，并发现未来太阳活动的后果以及更长时间尺度上太阳周期的强度。 美国国家科学基金会提供的资金将允许10至12名优秀研究生和青年科学家参加“4CESM”会议。通过AGU出版查普曼会议记录，在AGU的“地球物理研究杂志（空间物理）”上出版选定的会议论文，以及在AGU出版物“地球观测卫星”上发表摘要报告，将确保额外的社区影响。"

The Principal Investigator is a member of the committee that will organize a community workshop under the auspices of the American Geophysical Union (AGU), to be called the "Chapman Conference on the Causes and Consequences of the Extended Solar Minimum" ("4CESM"). The "4CESM" meeting will be held over 5 days in the summer of 2012 and will enable the interdisciplinary exchange of information and ideas concerning recent advances in measurement, theory, and numerical modeling in the solar and space physics communities. The "4CESM" meeting will provide a forum for interdisciplinary scientists to discuss their research about the current state of our understanding of the Sun's extreme minimum activity between solar cycles 23 and 24, as well as the potential effects of this minmum activity on the Earth. This unusual solar minimum provides a unique opportunity to assess the nature and structure of a very quiet Sun and a terrestrial upper atmosphere relatively devoid of solar influences. The overarching challenge for solar physics is to explain why this minimum happened, to determine how unusual it actually was, and to discover what the ramifications might be for future solar activity and the strength of the solar cycle on longer time scales. The funding provided by the National Science Foundation will allow 10 to 12 outstanding graduate students and young scientists to attend the "4CESM" meeting. Additonal community impact will be assured through AGU publication of the Chapman Conference proceedings, publication of selected conference papers in the AGU's "Journal of Geophysical Research (Space Physics)," and a summary report in the AGU publication "Eos."
