SCI: SEI +II: Towards a Virtual Solar-Terrestrial Observatory

该提案描述了虚拟日地观测站(VSTO)的原型开发，这是日地物理界的一个共享分布式基础设施。VSTO通过开发本体和模式、提供网络门户和分析工具以及数据同化工具，将能够在将NCAR的计算和存储资源与日地物理界连接在一起的网格环境中挖掘和处理大型分布式数据集。科学的目标用户领域是太阳、日地和空间物理(SSTSP)。广泛的影响和智力优势延伸到主要技术工作领域：本体论的开发将使现有语义元数据能够在跨学科环境中进行新的整合和合并，从而创建本体论及其维护工具；将通过利用NCAR正在进行的努力，如虚拟太阳天文台，开发和应用数据同化技术；在系统一级，作为新的分布式网络基础设施的业务原型，为更广泛的社区处理空间气象活动提供服务。

This proposal describes prototype development for a Virtual Solar-Terrestrial Observatory (VSTO), a shared distributed infrastructure for the solar-terrestrial physics community. The VSTO, through ontology and schema development, web portal and analysis tool provision, and data assimilation tools, will enable mining and processing of large distributed data sets in a grid environment linking together compute and storage resources at NCAR to the solar-terrestrial physics community. The targeted user field of science is solar, solar-terrestrial, and space physics (SSTSP).Broader impact and intellectual merit extend across the main technical work areas: ontology development will allow for new integration and merging of existing semantic metadata in an interdisciplinary setting with resulting tool creation for ontologies and their upkeep; data assimilation techniques will be developed and applied by leveraging ongoing efforts at NCAR, such as the Virtual Solar Observatory; and at the system level serve as an operational prototype for a new distributed cyberinfrastructure serving a broader community dealing with space weather activities.
