Collaborative Research: The North American Regional Climate Change Assessment Program (NARCCAP)--Using Multiple GCMs and RCMs to Simulate Future Climates and Their Uncertainty

北美区域气候变化评估计划(NARCCAP)的目标是：(1)开发和提供公开可用的多种高分辨率区域气候变化情景，用于影响和风险评估；(2)通过将区域气候模式(RCM)嵌套在较粗的空间尺度再分析数据产品中，评估区域模式在北美上空的表现；(3)了解关键的区域气候变化问题，如温室气体增加对极端天气事件各种类型频率的影响；(4)提高对区域气候模拟中关键问题的理解，包括方法方法；(5)对区域模型和全球气候模型(GCM)未来区域预测中的不确定性进行有限的检查；(6)在美国、加拿大和欧洲气候建模小组之间建立更大的合作，以利用各国的多样化建模能力；以及(7)协调美国、加拿大、欧洲和南美洲目前正在进行的各种区域和全球建模项目和计划，并从这些项目和计划中获得附加值。研究的广泛影响包括支持气候影响社区为公共政策提供决策相关信息，部分是通过面向用户的数据访问、格式化和模拟输出的归档设施。NARCCAP将通过编制区域范围的气候变化预测，为广泛的气候研究做出贡献。通过这样做，该计划将加强气候变化研究的基础设施，将北美和欧洲的几个机构连接在一个协作网络中，进行多模型模拟、输出分析和数据传播。该计划的成果将促进参与机构的本科生和研究生研究，并促进跨校园和机构之间的跨学科联系。由NSF支持的协作PI：Mearns，Linda O.，国家大气研究中心(LEAD)斯隆，Lisa C.，加州大学圣克鲁斯·古托斯基分校，William J.爱荷华州立大学Sain，Stephan R.，科罗拉多大学丹佛分校NOAA和美国能源部也支持NARCCAP协作PI：NOAA：Roads，John O.，加州大学圣地亚哥分校斯克里普斯海洋研究所DOE：Bader，David C.，Lawrence Livermore国家实验室，Lai-Yung(Ruby)，Battelle西北实验室，Philip B.，Lawrence Livermore国家实验室NSF赞助的国家大气研究中心和能源部劳伦斯·利弗莫尔国家实验室正在提供额外的实物支持。

The goals of The North American Regional Climate Change Assessment Program (NARCCAP) are to: (1) develop and make openly available, multiple high resolution regional climate change scenarios for use in impacts and risk assessments; (2) evaluate regional model performance over North America by nesting the Regional Climate Models (RCM) in coarser spatial scale reanalyzed data products; (3) understand critical regional climate change issues, such as the effects of increased greenhouse gases on the frequency of various types for extreme weather events; (4) enhance understanding of key issues in regional climate modeling, including methodological approaches; (5) conduct a limited examination of uncertainties in regional model and global climate model (GCM) future regional projections; (6) create greater collaboration between US, Canadian, and European climate modeling groups to leverage the diverse modeling capability across the countries; and (7) coordinate with and derive added value from diverse regional and global modeling projects and programs currently underway in the US, Canada, Europe, and South America.Broader impacts of the research include support for the climate impacts community to provide decision-relevant information for public policy, in part through a user-oriented data access, formatting and archival facility for output from the simulations. NARCCAP will contribute to a wide range of climate research by producing regional-scale projections of climate change. In doing so, the program will enhance the infrastructure for climate-change research by linking several North American and European institutions in a collaborative network for multi-model simulation, output analysis and data dissemination. The program's output will promote undergraduate and graduate research at the participating institutions and foster cross-disciplinary links across campuses and between institutions.
