Facility Support: Organizational Infrastructure for the Community Surface Dynamics Modeling System

社区表面动力学建模系统的组织基础设施NSF摘要-0621695社区表面动力学建模系统（CSDMS）是一个国家努力开发，支持和传播到地球科学研究和教学社区，集成软件，旨在预测侵蚀，运输和沉积物和溶质在景观及其储存库沉积盆地。CSDMS的目标是能够快速开发和应用针对特定流域-盆地演化问题和特定时空尺度的关联动力学模型。CSDMS企业将允许科学家、教育工作者和学生通过一个虚拟或数字图书馆参与进来，该图书馆包含不断发展和更新的模型、边界条件数据和教育包。将解决三个概念验证挑战：1）预测细沉积物和碳从景观中的源区到沉积盆地的运输和归宿，沉积盆地随着时间的推移积累沉积物; 2）了解人类对自然循环的影响，例如通过水道，森林火灾和农业实践的变化; 3）通过我们的地质历史跟踪景观和海景的演变，重点是更新世冰川循环。CSDMS将开发和维护计算系统，并确保地球表面模块的可移植性和互操作性，系统代码的计算效率以及文档和界面的清晰性和一致性。和兴趣为那些将从CSDMS产品中受益的人提供了所需的灵活性。模拟地球表面是一个与模拟海洋和大气动力学相当复杂的问题。这些社区的经验告诉我们，大型，复杂的数值模型的发展迅速成为整个研究社区的任务。社区方法允许有效地开发比任何单个小组开发的更强大的模型。CSDMS的基础设施提供了一个建模环境，以促进地球表面的研究在未来几十年内：赋予广泛的科学家和学生的社区与计算工具和跨学科的知识;简化的过程中的想法产生和假设检验通过链接的表面动力学模型;并使快速创建和应用模型定制特定的设置，科学问题和时间尺度。CSDMS将提供1）使用CSDMS计算系统的专业培训，2）加强本科地球科学教育的技术，（3）加强地球表面科学中学教学的工具，以及（4）向科学博物馆等公共机构提供非正式教育包。 该奖项由NSF GEO Directorate和OCE共同颁发。

Organizational Infrastructure for the Community Surface Dynamics Modeling SystemNSF Abstract for EAR-0621695The Community Surface Dynamics Modeling System (CSDMS) is a national effort to develop, support, and disseminate to the earth-science research and teaching community, integrated software aimed at predicting the erosion, transport, and deposition of sediment and solutes in landscapes and their repository sedimentary basins. The goal of CSDMS is to enable the rapid development and application of linked dynamical models tailored to specific landscape-basin evolution problems and at specific temporal and spatial scales. The CSDMS enterprise will allow individual scientists, educators and students to participate through a virtual or digital library of continuously evolving and linkable models, boundary condition data, and educational packages. Three proof-of-concept challenges will be addressed: 1) Predicting the transport and fate of fine sediment and carbon from source areas in the landscape to sedimentary basins that accumulate sediment over time; 2) Understanding the impact of humans on the natural cycle, through, for example, changes in waterways, forest fires, and agricultural practices; and 3) Tracking the evolution of landscapes and seascapes through our geological past, with focus on Pleistocene glacial cycles. The CSDMS will develop and maintain the computational system, and ensure the portability and interoperability of earth-surface modules, the computational efficiency of system code, and the clarity and consistency of documentation and interfaces.A community-based modeling environment, built of tools created by and provided for a broad spectrum of users with diverse aims, skills, and interests provides for the flexibility required by those who will benefit from CSDMS products. Modeling the surface of the Earth is a problem of comparable complexity to modeling oceanic and atmospheric dynamics. The experience of these communities teaches us that development of large, complex numerical models rapidly becomes a task for an entire research community. A community approach allows efficient development of models that are more powerful than any single group could develop. The CSDMS infrastructure provides a modeling environment to catalyze Earth-surface research over the coming decades by: empowering a broad community of scientists and students with computing tools and interdisciplinary knowledge; streamlining the process of idea generation and hypothesis testing through linked surface dynamics models; and enabling rapid creation and application of models tailored to specific settings, scientific problems, and time scales. CSDMS will provide 1) professional training in use of the CSDMS computational system, 2) technology to enhance undergraduate earth-science education, (3) tools for enhancing secondary-school teaching in earth-surface science, and (4) informal educational packages to public institutions such as science museums. This award is made jointly between EAR and OCE of the GEO Directorate, NSF.
