Arctic-CHAMP Project Office: The Arctic Community-Wide Hydrological Analysis and Monitoring Program

北极构成了一个独特而重要的环境，对地球系统的动态和进化至关重要。该地区目前正经历着迅速的环境变化。然而，人们对这种变化的来源和最终后果仍然知之甚少。作为NSF-ARCSS北极淡水整合研究（FWI）项目的一部分进行的研究不仅记录了北极水文循环的持续变化，而且还记录了这些变化在全球气候动力学中的重要作用。最近关于研究需要的文件强调了北极淡水过程在生态系统、社会和全球系统中的关键作用。最近发布的SEARCH实施计划（SEARCH, 2005）将淡水系统的变化描述为北极和地球系统之间最重要的联系之一。在2005年11月举行的第二次国际北极研究规划会议（ICARP II）上，11个工作组中有两个几乎完全把淡水动力学作为未来十年北极研究的最高优先事项。本提案中的工作将支持SEARCH的目标，并通过加强我们对北极圈尺度上北极系统变化的理解，为国际极地年做出贡献。本提案中所述工作的主要功能是维持北极-CHAMP科学管理办公室（SMO），扩大SMO的支持活动组合，将FWI普通员工最近确定的支持活动包括在内，以实现FWI综合，并协助ARCSS协调新兴的北极-CHAMP科学和外展工作。智力优势：北极- champ综合和整合问题是复杂和多方面的，一个专门的、管理良好的科学管理办公室是必要的，以提供一个有效的机制，促进项目参与者和其他相关研究活动之间的最大限度的合作和协调。FWI参与者的研究和整合活动现在已经很好地建立起来，并朝着最终通过泛北极的淡水循环实现对大气/陆地/海洋联系的广泛理解的有价值的综合进展；然而，正如我们所发现的，综合活动的协调对于实现最大的生产力和全系统规模的集成是必不可少的。SMO将具体地：支持北极- champ科学指导委员会正在进行的活动，催化跨FWI项目的合成，使FWI合成与ARCSS社区范围内的合成相关，组织北极- champ和FWI科学会议和专题讨论会，支持及时交付与champ相关的科学数据产品，并开发一个协调的FWI合成数据产品的adcc前档案，组织和举办2007年两次主要的FWI合成研讨会（为FWI研究人员）。与其他美国和国际机构合作伙伴进行联络活动，特别关注国际极地年和ICARP-II。向科学家和更广泛的用户社区传播Arctic-CHAMP的成果。

The Arctic constitutes a unique and important environment, central to the dynamics and evolution of the Earth system. The region is currently experiencing rapid environmental change. The sources and ultimate consequences of such change are, however, still poorly understood. Research conducted as part of the NSF-ARCSS Arctic Freshwater Integration Study (FWI) program has documented not only the ongoing changes in the arctic hydrological cycle, but also the important role these changes play in global climate dynamics. Recently developed documents on research needs have emphasized the critical function of arctic freshwater processes in ecosystem, social and global systems. The recently released SEARCH Implementation Plan (SEARCH, 2005) describes changes in the freshwater system as one of the most consequential links between the arctic and the earth systems. Two of eleven working groups in the November 2005 International Conference on Arctic Research Planning II (ICARP II) focused almost exclusively on freshwater dynamics as the highest priority for the next decade of arctic research. The work in this proposal will support the goals of SEARCH and contribute to IPY through enhancing our understanding of the changing arctic system on circumpolar scales. The primary function of the efforts described in this proposal is to maintain the Arctic- CHAMP Science Management Office (SMO), expand the SMO portfolio of support activities to include those recently identified by the FWI rank-and-file to realize the FWI Synthesis, and to assist ARCSS in coordinating emerging Arctic-CHAMP science and outreach efforts.Intellectual Merit: The Arctic-CHAMP synthesis and integration issues are complex and multi-faceted and a dedicated, well-managed, Science Management Office is necessary to provide an efficient mechanism for facilitating maximum collaboration and coordination among project participants and other related research activities. The research and integration activities of the FWI participants is now well established and progressing towards ultimately achieving a valuable synthesis of broad-scale understanding of atmospheric/terrestrial/oceanic connections through the freshwater cycle of the pan- Arctic; however, and as we have found, coordination of synthesis activities is essential to achieve maximum productivity and full-system scale integration. The SMO will specifically:Support the ongoing activities of the Arctic-CHAMP Scientific Steering CommitteeCatalyze synthesis across FWI projects and make FWI synthesis relevant to ARCSS community wide synthesisOrganize Arctic-CHAMP and FWI scientific meetings and symposiaSupport the timely delivery of CHAMP-related science data products and develop a coordinatedpre-ADCC archive of FWI synthesis data productsOrganize and conduct two major FWI synthesis Workshops in 2007 (for FWI investigators) and 2008 (as an IPY-affiliated meeting), including the exercise of the FWI synthesis compendiumConduct liaison activities with other US and international agency partners, with a special focus on IPY and ICARP-II.Disseminate findings of Arctic-CHAMP effort, to scientists and broader user communities.
