EarthCube Building Blocks: Earth System Bridge: Spanning Scientific Communities with Interoperable Modeling Frameworks

该EarthCube项目在地球科学建模架构的开发、实施和支持以及在模型开发和数据管理中促进和利用社区标准方面拥有深厚的学科和跨学科专业知识。结合起来，这个团队将把现有的模型架构、模型耦合标准和数据标准整合到一套开源的地球系统桥构建块中，这些构建块将改变地球系统模型耦合的过程，并弥合目前的技术差距。该小组将与框架开发人员社区合作，创建一种框架定义语言(FDL)，从元数据使用、体系结构、相互作用协议和实施等方面说明地球系统耦合技术的特点，并将其作为了解潜在框架相互联系的基础。他们将利用解放卢旺达民主力量开发一套？桥梁？它将联邦建模企业和学术地球科学建模企业的主要软件框架连接起来，以便创建无缝的环境和影响预测工具，并开发新的服务，以改进机构间四维数据库与更多不同类型的学术数据库的整合，供地球系统模型和建模小组使用。将在两个案例研究中演示新的建模和数据集成架构：第一个案例研究预测飓风桑迪登陆对当地的影响；第二个案例研究将地球深部过程与地表动力学相结合。这些问题跨越学科、机构以及研究和运营社区，需要解决科学、技术和文化问题。总体目标是弥合目前地球系统建模方面的技术差距，从而说明如何在不同的地球科学学科和社区中使用共同的网络基础设施，以及改进的网络基础设施如何直接解决紧迫的跨学科科学问题。地球系统桥开发的工具有可能服务于许多不同的学科社区。一个更相互联系和更有能力的模型界将大大提高目前在研究界和业务界之间转移知识的速度，连接学术和业务界的基础设施将减少目前系统中存在的低效和差距。所开发的技术将使更多的地球科学家获得更高的能力，降低更多科学家参与多学科研究的门槛，这些研究是解决当今需要解决的政策问题并提高我们国家对各种自然灾害的适应能力所必需的。

This EarthCube project possesses deep, disciplinary and interdisciplinary expertise in the development, implementation and support of geoscientific modeling architectures and in the promotion and utilization of community standards in model development and in data management. Combined, this team will integrate existing model architectures, model coupling standards and data standards into a set of open source Earth System Bridge building blocks that will transform the process of Earth system model coupling and bridge the present technological gap. In collaboration with the community of framework developers, the team will create a Framework Definition Language (FDL) which characterizes Earth system coupling technologies in terms of their metadata usage, architecture, protocols for interaction, and implementation, and use this as a basis for understanding potential framework inter-connections. They will use the FDL to develop a set of ?bridges? that connect leading software frameworks from the federal modeling enterprise and from the academic geoscientific modeling enterprise, for the sake of creating seamless environmental and impacts prediction tools, and develop new services to improve the integration of inter-agency, four-dimensional databases with more heterogeneous academic databases for use in earth system models and by modeling groups. Demonstration of the new modeling and data integration architecture will be in two case studies: the first, prediction of the local impacts of the Hurricane Sandy landfall; and the second, the integration of deep Earth process with surface dynamics. These problems span disciplines, agencies, and research and operational communities, and require addressing scientific, technical, and cultural issues.The overarching goal is to bridge this present technological gap in Earth System modeling, thereby illustrating how a common cyberinfrastructure can be used in different Earth science disciplines and communities, and how improved cyberinfrastructure can directly address pressing cross-disciplinary science questions.The tools developed by the Earth System Bridge have the potential to serve many different disciplinary communities. A more interconnected and capable modeling community will significantly increase the speed at which knowledge is currently transferred between the research and operational communities, Connecting the academic and operational infrastructure will reduce inefficiencies and gaps that exists in the system today. The technology developed will place increased capabilities in the hands of a broader set of geoscientists, lowering the barriers to more scientists participating in multi-disciplinary research that is needed to address today?s policy issues and increase our national resilience to a wide variety of natural hazards.
