Facilitating Arctic System Science using the Community Earth System Model

地球系统模型是了解未来几年和几十年地球气候变化的关键工具之一，但现有地球系统模型的复杂性和不可访问性是其广泛使用的障碍。与其他努力不同，共同体地球系统模型(CESM)的源代码和输出可通过支持的公开发布免费获得，并鼓励广大科学界参与模型开发、分析和实验设计。该项目将通过为极地科学联络员提供支持，促进社区广泛参与专门针对北极科学应用的CESM。拟议的联络活动针对所有类型的科学家，包括那些需要一对一援助的新的地球系统模型研究人员。该项目支持的联络活动将有三个主要重点：1)通过主办访问、有重点的会议和合作活动，吸引和扩大CESM极地科学研究社区；2)在CESM的使用、分析和开发方面为北极科学家提供直接支持；以及3)支持和提供CESM与北极科学有关的应用。该项目将在模型细节、可用于解决特定研究问题的配置以及关于CESM实验设计的信息方面对感兴趣的科学家进行培训。将开发和提供极地气候诊断工具，以便于对CESM综合情况进行分析。由该社区设计的旨在解决理解北极变化的各个方面的实验将通过一个带有数据和诊断图表链接的门户网站进行并提供。通过与普通公众、媒体和NCAR教育和外联办公室的互动进行外联，将使该项目资助的活动具有广泛的影响。

Earth System Models are one of the key tools for understanding how Earth's climate will change over the coming years and decades, but the complexity and inaccessibility of existing earth system models are a barrier to their widespread use. Unlike other efforts, the Community Earth System Model (CESM) source code and output are freely available through supported public releases and the broad science community is encouraged to participate in model development, analysis, and experimental design. This project will facilitate broad community involvement in CESM specifically for Arctic science applications by providing support for a polar science liaison. The proposed liaison activities target all types of scientists, including those new to earth system model research that require one-on-one assistance. The liaison activities supported under this project will have three primary foci: 1) Engaging and expanding the CESM polar science research community through hosted visits, focused meetings, and collaborative activities, 2) Providing direct support to Arctic scientists in the use, analysis, and development of CESM, and 3) Supporting and making available Arctic science related applications of CESM. The project will educate interested scientists in model specifics, the configurations available to address particular research questions, and information on CESM experimental design. Polar climate diagnostic tools will be developed and made available to enable easy analysis of CESM integrations. Experiments, designed by the community to address aspects of understanding Arctic change, will be performed and made available through a web portal with links to data and diagnostic plots. Outreach through interactions with the general public, the media, and the NCAR Education and Outreach office will allow the activities funded under this project to have a broad reach.
