This is a proposal for continued support of the International Arctic Research Center (IARC) at the university of Alaska Fairbanks. Under the theme of Climate of the Arctic: Modeling and Processes (CAMP), IARC will fill needed roles in arctic climatic research by using its unique international character to integrate and synthesize across discipline boundaries, thereby forming a connection between the arctic modeling and global modeling communities. IARC's projects are intended to enhance strategic collaboration for IARC's synthesis and integration efforts by international researchers who have agreed to participate in IARC's efforts. The present renewal proposal outlines research plans, and provides specific descriptions of the activities planned for the first year. Research areas central to the IARC effort include (1) permafrost/frozen-soil modeling, in which state-of-the-art soil hydrology and thermodynamic formulations will draw upon comprehensive field measurements and integrated datasets of permafrost, including data from the Barrow Permafrost Observatory; (2) changes of arctic biota/vegetation, for which pan-Arctic data will be used to drive simulations of changes in vegetative cover, the role of disturbance (e.g., fire), and feedbacks to externally forced climate change; (3) Arctic Ocean/sea ice studies in which the intersection of core activities (the Arctic Ocean Model Intercomparison Project and the Nansen-Amundsen Basin Observational System) will provide new insights into the disposition and variability of Atlantic water inflow to the Arctic; and (4) studies of arctic atmospheric processes that are central to simulating and projecting climate change, including studies of cloud-radiative and moisture feedbacks, changes in extreme events (e.g., floods, droughts, storms), and strategies for downscaling coarse-resolution model output to the Arctic. The international dimension will be enhanced by collaborative projects with Japanese scientists. Outreach activities will include the Arctic Climate Impact Assessment (ACIA), for which the Secretariat is at IARC.

这是阿拉斯加费尔班克斯大学国际北极研究中心（IARC）持续支持的提案。在北极气候的主题下：建模和过程（CAMP），IARC通过使用其独特的国际特征来整合和合成跨学科的边界，从而在北极气候研究中填补所需的角色，从而在北极建模与全球建模之间形成联系社区。 IARC的项目旨在增强国际研究人员同意参加IARC的努力的IARC综合和整合工作的战略合作。目前的续签提案概述了研究计划，并提供了第一年计划的活动的具体描述。 IARC工作中心的研究领域包括（1）（1）永久冻土/冷冻土壤建模，其中最先进的土壤水文和热力学配方将利用全面的现场测量和多年冻土的集成数据集，包括来自Barrow Permafrost Permafrost的数据天文台; （2）北极生物群/植被的变化，为此，将使用泛氧化数据来模拟营养覆盖的变化，干扰的作用（例如火灾）以及对外部强迫气候变化的反馈； （3）北极海洋/海冰研究，其中核心活动的相交（北极海洋模型比较项目和Nansen-Amundsen盆地观察系统）将为大西洋水流流入北极的倾向和变化提供新的见解； （4）对模拟和预测气候变化至关重要的北极大气过程的研究，包括研究云辐射性和水分反馈，极端事件的变化（例如，洪水，干旱，风暴）以及降低粗分辨率的策略模型输出到北极。与日本科学家的协作项目将增强国际维度。外展活动将包括北极气候影响评估（ACIA），秘书处在IARC上。
