This is a 3-year effort to continue and expand the operation and utility of the SuperMAG facility. SuperMAG is a data collection, processing, and distribution service for ground-based magnetic field perturbation measurements. It was established by the PI and his team under an existing 3-year NSF grant, AGS-0646323, which expires at the end of April 2010. Through a worldwide collaboration of organizations and national agencies the facility currently includes data from more than 250 ground-based magnetometers and covers the time span from 1997 through 2001. Via a user friendly website it provides measurements of magnetic field perturbations from all available stations in the same coordinate system, with identical time resolution and a common baseline removal approach. The service has been publicly available since January 2009. The worldwide distribution of ground-based magnetic field variation measurements has been a backbone of magnetospheric and ionospheric research since the very beginning of the field. It continues to be a valuable resource for a wide range of science investigations, providing one of the few available means of assessing the global dynamics of the Magnetosphere-Ionosphere system and addressing questions of cross-scale coupling. The goal of this project is to further develop the SuperMAG service for the benefits of the science community as well as students, teachers and the general public. Specifically, the facility will be enhanced in the following ways: 1) Expand the data-holdings to include the years 2002-2010 and 1996; 2) Expand the spatial coverage by including data from a list of new SuperMAG collaborators; 3) Develop additional user-friendly tools for analysis and education and public outreach (EPO). The proposed effort will build on the existing comprehensive infrastructure to include an additional 10 years of 1-min data from ~250 stations for a total of ~2500 years of validated, rotated and base-lined magnetometer data.This project being for the operation and further development of a public science data service facility, by design, has strong broader impacts. Having only been operational for a short time (less than a year on line) it has already attracted a good number of users (more than 100 individual registered users) and shows a steadily increasing trend in usage. The planned enhancements in data holdings and flexible user specified data products are certain to increase usage even further. The facility undertakes several initiatives specifically aimed at involving students and teachers at all levels both as users and developers of the service. The Collaboration with a large and diverse international group of data providers is at the heart of the facility. This collaboration will be further expanded and strengthened through this next installment of the project.

这是一项为期3年的努力，旨在继续和扩大SuperMAG设施的运营和用途。SuperMAG是一家用于地面磁场扰动测量的数据收集、处理和分发服务。它是由PI和他的团队在现有的3年期美国国家科学基金会拨款AGS-0646323下建立的，该拨款将于2010年4月底到期。通过各组织和国家机构的全球协作，该设施目前包括250多个地面磁力计的数据，涵盖1997年至2001年的时间跨度。通过一个用户友好的网站，它提供了同一坐标系中所有可用站点的磁场扰动测量结果，具有相同的时间分辨率和通用的基线消除方法。这项服务自2009年1月以来一直公开提供。从该领域一开始，地面磁场变化测量的全球分布就一直是磁层和电离层研究的支柱。它仍然是广泛科学调查的宝贵资源，为评估磁层-电离层系统的全球动态和解决跨尺度耦合问题提供了为数不多的手段之一。该项目的目标是进一步发展SuperMAG服务，造福于科学界以及学生、教师和普通公众。具体地说，将通过以下方式加强该设施：1)扩大数据持有量，将2002-2010年和1996年包括在内；2)通过纳入SuperMAG新合作者名单中的数据，扩大空间覆盖面；3)开发更多用户友好的分析和教育工具，以及公共宣传(EPO)。拟议的工作将建立在现有综合基础设施的基础上，包括来自约250个站点的额外10年的1分钟数据，总共约2500年的经过验证的、旋转的和基线的磁力仪数据。该项目旨在运营和进一步发展公共科学数据服务设施，其设计具有强大的更广泛的影响。它只运行了很短的时间(上线不到一年)，就已经吸引了相当数量的用户(超过100名个人注册用户)，并显示出稳步增长的使用趋势。计划中的数据持有量增强和灵活的用户指定数据产品肯定会进一步增加使用量。该设施采取了几项举措，专门旨在让各级学生和教师作为该服务的用户和开发者参与进来。与一个庞大而多样的国际数据提供商集团的合作是该设施的核心。通过该项目的下一期工作，这一合作将得到进一步扩大和加强。
