Collaborative Research, IPY: A Cooperative Arctic Data and Information Service (CADIS)

提案标题：合作研究，IPY：合作北极数据和信息服务（CADIS）机构：国家大气研究中心摘要日期：2006年12月19日摩尔：0632313该项目将开发一个合作北极数据和信息服务（CADIS），将支持北极观测网络（AON）和北极环境变化研究（STAR）计划。CADIS将通过提供近实时数据交付、数据存储库、发现门户和数据操作工具来发现、访问和使用科学数据。这一系统和数据服务将以逐步连贯的方式建立，并最终实现对北极科学数据的全面长期管理。CADIS将是大学大气研究公司（UCAR），国家冰雪数据中心（NSIDC）和国家大气研究中心（NCAR）的共同努力。项目团队将通过利用、集成和扩展UCAR的社区数据门户（CDP）框架和Unidata的THREDDS环境来开发一个新的网络基础设施，以形成CADIS系统和门户。CADIS门户网站将使科学家更容易定位、显示、子集、发布和分析数据提供商网络提供的相关数据集。第一年将完成元数据计划，其中将包括AON项目和长期观测站（LTO）项目。在第二年，CADIS门户网站将填充AON和LTO项目的元数据。在第三年，将通过CADIS实时提供选定的AON和IASOA（国际北极大气观测系统）数据，并将增加通过地图界面进行搜索的工具，以及显示选定的AON或IASOA组件位置的地图服务器（如果有元数据）。同样在第三年，将评估和记录系统性能，并绘制未来方向。科学界和非专业用户的指导将是实施CADIS设施的关键。将通过问卷调查、会议、常设委员会和个别询问收到信息，以评估CADIS的有效性并提出改进建议。该项目与国际极地年制定全面数据管理计划和创建遗留数据集的目标高度相关。其智力价值在于逐步开发一个新的网络基础设施，用于管理北极科学数据。CADIS更广泛的影响是，它为北极科学界和其他用户长期访问数据档案、发现、交付和分析奠定了基础。

Proposal Title: Collaborative Research, IPY: A Cooperative Arctic Data and Information Service (CADIS)Institution: National Center for Atmospheric ResearchAbstract date: 12/19/06Moore: 0632313This project will develop a Cooperative Arctic Data and Information Service (CADIS) that will support the Arctic Observing Network (AON) and Study of Environmental Arctic Change (SEARCH) programs. CADIS will provide the discovery, access, and use of scientific data by providing near-real-time data delivery, a repository for data storage, a portal for the discovery, and tools to manipulate data. This system and data service will be built in a stepwise coherent manner and result in comprehensive long-term management for Arctic scientific data. CADIS will be a joint effort of the University Corporation for Atmospheric Research (UCAR), the National Snow and Ice Data Center (NSIDC), and the National Center for Atmospheric Research (NCAR). The project team will develop a new body of cyberinfrastructure by leveraging, integrating, and extending UCAR's Community Data Portal (CDP) framework and Unidata's THREDDS environment to form the CADIS system and portal. The CADIS portal will make it easier for scientists to locate, display, subset, publish, and analyze related data sets provided by a network of data providers. In the first year, a metadata plan will be completed; it will include AON projects and Long Term Observatory (LTO) projects. In the second year, the CADIS portal will be populated with metadata from the AON and LTO projects. In the third year, real-time delivery through CADIS of selected AON and IASOA (International Arctic System for Observing the Atmosphere) data will be accomplished, and tools for searching via a map interface, and a map server showing the location of selected AON or SEARCH components (where metadata are available) will be added. Also in the third year, system performance will be evaluated and documented, and a future direction charted. Guidance from the scientific and lay user communities will be key to implementing the CADIS facility. Information will be received via questionnaires, meetings, standing committees and individual queries to assess CADIS effectiveness and recommend improvements. This project is highly relevant to International Polar Year goals for developing comprehensive data management plans and creating legacy data sets. The intellectual merit lies in the stepwise development of a new cyberinfrastructure for management of Arctic scientific data. The broader impact of CADIS is that it creates a foundation for long-term access to data archives, discovery, delivery and analysis by the Arctic science community and other users.
