Computational Infrastructure for the Community Surface Dynamics Modeling System

社区表面动力学建模系统（CSDMS）支持不同社区的专家谁模拟地球表面过程。它通过开发、支持和传播集成软件模块来实现这一目标，这些模块可以预测流体的运动，以及景观及其沉积盆地中沉积物和溶质的通量（产生、侵蚀、运输和沉积）。CSDMS提供开放的数值模型访问，为建模者维护数据，为教师维护地球科学建模教育资源，为会员提供计算资源，为高级模型耦合提供帮助，是地球科学研究的讨论平台。此计划旨在加强CSDMS的网络基础设施。当前的CSDMS建模框架将被扩展，以便在web浏览器、更广泛的计算平台和其他高性能计算集群中使用，以确保框架的健壮性和可持续性。社区生成的模型将转换为“即插即用”模式。通过开发组件自动化包装工具。将采用量化模型不确定性的方法。基准数据将被纳入CSDMS建模框架，以支持模型之间的相互比较。最后，还将在建模框架中开发用于摄取和利用语义中介数据库的健壮机制。此外，将推行六项新的社区倡议：1)地球-生态系统建模倡议，以捕捉生态系统动力学及其与景观的相互作用；2)地球动力学倡议，调查气候、地貌和构造过程之间的相互作用；3)人类世建模倡议，纳入人类影响的机制模型；4)沿海脆弱性建模倡议，重点关注三角洲及其多重威胁和压力源；5)大陆边缘建模倡议；捕捉墨西哥湾产生浊流的极端海洋和大气事件；6)CZO焦点研究小组，开发CSDMS架构和协议与关键带天文台开发的模型和数据之间的兼容性。CSDMS简化了无数社会相关过程的计算机建模，包括冰川融化、山体滑坡、侵蚀、湿地演变、水循环、洪水和海岸变化。通过其社区支持机制，CSDMS催化了想法产生和假设检验的过程，使模型能够针对特定环境、科学问题和时间尺度快速创建和应用。CSDMS吗?社区方法允许有效地开发模型，这些模型比任何单个小组开发的模型更强大。冗余减少了，模型得到了更好的审查，创新能力得到了扩展，精力可以集中在代表性不足或有争议的地球表面领域。CSDMS通过征求和发布模型文档来确保模型是可访问的和透明的。CSDMS集成设施的工作人员将模型转换为可以轻松耦合在一起的模块；这种模块化产生了现有软件的新应用程序。这项新合同将使CSDMS能够通过开发：1)可访问、易于使用和相关的软件产品和方法，2)跨多个学科推进地球表面过程建模的新社区倡议，以及3)针对不同入门级的教育产品和培训讲习班来增强其网络基础设施。

The Community Surface Dynamics Modeling System (CSDMS) supports a diverse community of experts who model Earth surface processes. It does so by developing, supporting, and disseminating integrated software modules that predict the movement of fluids, and the flux (production, erosion, transport, and deposition) of sediment and solutes in landscapes and their sedimentary basins. CSDMS provides open-access to numerical models, maintains data for modelers and educational resources on earth science modeling for teachers, provides computing resources for members, offers help in advanced model coupling, and is a platform of discussion for earth science research.This project aims to enhance the CSDMS cyber-infrastructure. The current CSDMS Modeling Framework will be extended for use within a web browser, on a wider variety of computational platforms, and on other high performance computing clusters to ensure robustness and sustainability of the framework. Community-generated models will be converted into ?plug-and-play? components through the development of automated wrapping tools. Methods for quantifying model uncertainty will be adapted. Benchmarking data will be incorporated into the CSDMS modeling framework to support model inter-comparison. Finally, a robust mechanism for ingesting and utilizing semantic mediation databases will also be developed within the Modeling Framework. In addition, six new community initiatives will be pursued: 1) an Earth - ecosystem modeling initiative to capture ecosystem dynamics and ensuing interactions with landscapes, 2) a geodynamics initiative to investigate the interplay among climate, geomorphology, and tectonic processes, 3) an Anthropocene modeling initiative, to incorporate mechanistic models of human influences, 4) a coastal vulnerability modeling initiative, with emphasis on deltas and their multiple threats and stressors, 5) a continental margin modeling initiative, to capture extreme oceanic and atmospheric events generating turbidity currents in the Gulf of Mexico, and 6) a CZO Focus Research Group, to develop compatibility between CSDMS architecture and protocols and Critical Zone Observatory-developed models and data.CSDMS streamlines the computer modeling of myriad societally relevant processes, including melting glaciers, landslides, erosion, wetland evolution, water cycling, flooding, and coastal change. Through its community support mechanisms, CSDMS catalyzes the process of idea generation and hypothesis testing, enabling the rapid creation and application of models tailored to specific settings, scientific problems, and time scales. CSDMS? community approach allows the efficient development of models that are more powerful than could be developed by any single group ? redundancy is reduced, models are better vetted, the capability for innovation is expanded, and energy can be focused towards earth-surface domains that are poorly represented or controversial. CSDMS ensures that models are accessible and transparent by soliciting and publishing model documentation. Staff at the CSDMS Integration Facility convert models into modules that can be easily coupled together; this modularity gives rise to new applications for existing software. This new award will enable CSDMS to enhance its cyber-infrastructure by developing: 1) software products and approaches designed to be accessible, easy to use, and relevant, 2) new community initiatives to advance earth-surface process modeling across many disciplines, and 3) educational products and training workshops aimed at various entry levels.
