American Geophysical Union (AGU) Chapman Conference on Dayside Magnetosphere Interactions; Chengdu, China; July 10-14, 2017

本提案要求为参加2017年7月10日至14日在中国成都举行的为期五天的查普曼日侧磁层相互作用会议的参与者（包括学生、早期职业科学家和没有必要经济手段的特邀演讲者）提供差旅支持。会议的重点是关于太阳风的质量、动量和能量如何穿透朝向太阳的地球磁层的开放性问题。这些潜在的机制是导致地球周围空间天气扰动发展的原因。讲习班之所以及时举行，除其他外，是因为有越来越多的从正在运行的科学卫星收集的多点观测资料，以及利用近地轨道卫星阵列和地面仪器网络构建全球电动力参数图的新技术。此外，通过比较太阳风等离子体在地球和其他行星上的穿透机制，有望获得新的见解。国际讲习班对取得进展特别有价值，因为许多合并的数据集是国际合作的结果。查普曼会议有着悠久的历史，它成功地将国际研究人员（和学生）聚集在一个研讨会式的氛围中，解决科学前沿的开放性问题。这样的环境混合了各种各样的观点和不同的参与者，为具有实现突破潜力的新创新方法提供了一个已知的孵化器。这种环境也为学生提供了宝贵的教育经验和国际交流的机会。会议结束后，会议记录将发表在美国地球物理联合会（AGU）地球物理专论系列的一卷中，预计将记录这一科学领域的现状。只有百分之几的太阳风击中地球的磁层，实际上穿透了我们的磁屏障。然而，这一小部分是整个地球空间和高层大气中危险空间天气干扰发展的原因。了解这种渗透发生的方式将有助于改进对空间天气干扰的预测，并有助于解决以保护和/或减轻对关键的易受空间影响的社会基础设施的损害为重点的国家优先事项。

This proposal is requesting travel support for participants (including students, early career scientists, and invited speakers without the necessary financial means) to participate in a five-day Chapman Conference on Dayside Magnetosphere Interactions to be held in Chengdu, China on 10-14 July 2017. The conference is focused on open questions about the manner in which solar wind mass, momentum, and energy penetrate into the Earth's magnetosphere on its sunward-facing side. The underlying mechanisms are responsible for the development of space weather disturbances around Earth. The workshop is timely due, among other things, to the availability of a growing collection of multi-point observations from operating scientific satellites and new techniques for constructing global maps of electrodynamic parameters from both satellite arrays in low earth orbit and instrument networks on the ground. In addition, new insights are expected from comparing mechanisms for the penetration of solar wind plasma at Earth to those at other planets. An international workshop is particularly valuable for progress because many of the combined data sets are the result of international collaborations. Chapman conferences have a long history of successfully bringing together international researchers (and students) in a workshop style atmosphere to address open questions at scientific frontiers. Such an environment, which intermixes a wide variety of viewpoints and diverse participants, provides a known incubator for new and innovative approaches that have the potential for enabling breakthroughs. This environment is also a valuable educational experience for students and an opportunity for international networking. Following the meeting, proceedings will be published in a volume of the American Geophysical Union (AGU) Geophysical Monograph Series, which is expected to document the state of the field in this scientific area.Only a few percent of the solar wind striking the Earth's magnetosphere actually penetrates through our magnetic barrier. However, this small amount is responsible for the development of dangerous space weather disturbances throughout Geospace and the upper atmosphere. Understanding the manner by which this penetration occurs will lead to improved forecasting of space weather disturbances and help to address a national priority focused on protecting and/or mitigating damage to critical space-vulnerable societal infrastructures.
