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

该提案描述了虚拟日地观测台（VSTO）的原型开发，这是日地物理学界共享的分布式基础设施。 VSTO通过本体和模式开发、门户网站和分析工具提供以及数据同化工具，将能够在网格环境中挖掘和处理大型分布式数据集，将NCAR的计算和存储资源与日地物理学社区联系在一起。 目标用户科学领域是太阳、日地和空间物理学，其广泛影响和知识价值延伸到各主要技术工作领域：本体论开发将允许在跨学科环境中对现有语义元数据进行新的整合和合并，从而为本体论及其维护创建工具;将通过利用NCAR正在进行的努力，如虚拟太阳观测站，开发和应用数据同化技术;并在系统一级充当新的分布式网络基础设施的运行原型，为处理空间气象活动的更广泛群体服务。

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.
