American Geophysical Union (AGU) Chapman Conference on Currents in Geospace and Beyond; Dubrovnik, Croatia; May 22-27, 2016

该提案要求为与会者出席将于2016年5月22日至27日在克罗地亚杜布罗夫尼克举行的AGU查普曼地球空间及以外海流会议提供差旅费。 查普曼会议是由美国地球物理联合会主办的专题会议，旨在为详细的科学讨论提供机会，这在秋季AGU会议等大型会议上是不可能的。 这笔资金将主要用于美国学生和年轻研究人员，但必要时也可用于受邀演讲者。自上次查普曼会议以来，由于观测和全球模式的进展，新的知识已经积累了16年。 这个时机是适当的，可以将研究人员聚集在一起，更清楚地了解该领域的状况、未决问题、所需的新观测和全球模型的能力。这次会议将使美国学生和早期职业科学家能够与国际专家会面并建立联系。 会议专著将提供一个最新的研究状态和悬而未决的问题，这是有价值的研究和教育目的。 空间中的电流是会议的焦点，是近地空间、太阳、其他行星和天体物理物体中等离子体和磁场结构发展的关键。 会议有三个目标，即：（1）加深对空间等离子体中电流的了解，（2）利用新的多卫星数据集、新的和扩大的地面设施以及1999年关于这一专题的上一次会议期间没有的下一代全球模型，以及（3）通过促进在截然不同的空间环境中研究电流的研究人员之间的互动来丰富讨论（即，太阳、行星和地球）。 观察、模型和研究人员本身就是国际性的。 预计将有120-140名科学家参加。

This proposal requests travel funds for participants to attend the AGU Chapman Conference on Currents in Geospace and Beyond, which will be held 22-27 May 2016 in Dubrovnik, Croatia. Chapman Conferences are topical meetings sponsored by the American Geophysical Union that are designed to provide opportunities for detailed scientific discussion that is not possible at large meetings such as the Fall AGU meeting. This funding will be used mainly for U.S. students and young researchers but may be used for invited speakers if necessary. New knowledge has been accumulating over the sixteen years since the last Chapman conference on this topic due to progress in observations and global models. The timing is appropriate to bring together researchers to develop a clearer understanding of the state of the field, the open questions, the needed new observations and the capabilities in global models. This conference will enable U.S. students and early career scientists to meet and network with international experts. The conference monograph will provide an up-date look at the state of the research and at the outstanding unsolved questions, which is valuable for both research and education purposes. Electric currents in space, the focus of the conference, are key to the plasma and magnetic field structures that develop in near-Earth space, at the Sun, at other planets, and in astrophysical objects. The conference has three objectives, namely: (1) to deepen understanding of electric currents in space plasmas, (2) to leverage new multi-satellite data sets, new and expanded ground-based facilities and next-generation global models that were not available during the previous conference on this topic in 1999, and (3) to enrich the discussion by fostering an interaction between researchers who study currents in vastly different space environments (i.e., the Sun, planets and Earth). The observations, models and researchers are inherently international. Attendance is anticipated to be 120-140 scientists.
