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

首席调查员是将在美国地球物理联合会(AGU)主持下组织一次社区讲习班的委员会成员，该讲习班将被称为“延长太阳活动极小期的原因和后果查普曼会议”(“4CESM”)。“4CESM”会议将于2012年夏季举行，为期5天，将有助于就太阳和空间物理界在测量、理论和数值模拟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，讨论他们关于我们对太阳在第23至24周之间极端最小活动的理解现状的研究，以及这一最小活动对地球的潜在影响。这一不同寻常的太阳极小期提供了一个独特的机会来评估非常安静的太阳和相对没有太阳影响的地球高层大气的性质和结构。太阳物理学面临的最大挑战是解释为什么会出现这种极小值，确定它实际上有多不寻常，并发现它可能会对未来的太阳活动和更长时间尺度上的太阳周期强度产生什么影响。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。将通过以下方式确保社区的其他影响：AGU出版查普曼会议论文集，在AGU的“地球物理研究(空间物理)杂志”上发表选定的会议论文，并在AGU出版物“Eos”上发表摘要报告。

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."
