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

社区表面动力学模拟系统的组织结构NSF EAR摘要-0621695社区表面动力学模拟系统(CSDMS)是一项全国性的工作，旨在开发、支持和向地球科学研究和教学社区传播旨在预测景观及其储存库沉积盆地中沉积物和溶质的侵蚀、迁移和沉积的集成软件。CSDMS的目标是能够在特定的时间和空间尺度上，针对特定的景观-盆地演化问题，快速开发和应用相互关联的动力学模型。CSDMS企业将允许个别科学家、教育工作者和学生通过虚拟或数字图书馆参与，其中包括不断演变和可链接的模型、边界条件数据和教育资料包。将解决三个概念验证挑战：1)预测细微沉积物和碳从地貌源区到沉积盆地的运移和命运；2)了解人类对自然循环的影响，例如通过水道、森林火灾和农业做法的变化；3)跟踪我们过去地质情况的景观和海景的演变，重点是更新世冰川周期。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度和一致性。基于社区的建模环境由具有不同目标、技能和兴趣的广泛用户创建并提供，为那些将受益于CSDMS产品的人提供所需的灵活性。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，开发大型、复杂的数值模型迅速成为整个研究社区的一项任务。社区方法允许高效地开发比任何单个组织所能开发的更强大的模型。CSDMS基础设施提供了一个模拟环境，通过以下方式促进未来几十年的地球表面研究：赋予广大科学家和学生以计算工具和跨学科知识的能力；通过链接的表面动力学模型简化想法产生和假设检验的过程；并能够快速创建和应用针对特定环境、科学问题和时间尺度的模型。CSDMS将提供1)使用CSDMS计算系统的专业培训，2)加强本科生地球科学教育的技术，(3)加强中学地球表面科学教学的工具，以及(4)向科学博物馆等公共机构提供非正式教育包。该奖项是由EAR和国家科学基金会地球观测组织理事会的OCE共同颁发的。

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.
