Science-Driven Cyberinfrastructure: Integrating permafrost data, services, and research applicationsThis project proposes the use of cyberinfrastructure tools for providing services to the scientific community for accessing and discovering selected permafrost datasets. Permafrost is deemed as an Environmental Indicator and an Essential Climate Variable by agencies monitoring the Earth?s climate. Improved access to permafrost datasets (currently scattered over many places on the web) is necessary for better understanding its current and past state. Global scientific and policy communities need comprehensive, up-to-date maps of permafrost distribution and status. By making permafrost data easier to use, this project supports data integration work currently duplicated by every lab using permafrost data and will advance knowledge by freeing critical time for unique research. Project outcomes are directly useful to policy-makers, broader science researchers, indigenous communities, community-based monitoring programs, and others living on or in close proximity to and studying permafrost. Through science-driven cyberinfrastructure, the research team will produce a set of scalable, multi-faceted services to address the complexity of permafrost data access and usability. Recognizing the importance of coordinated efforts in this area, the project will start where previous efforts left off. This research leverages progress in International Permafrost Association and Global Terrestrial Network - Permafrost (GTN-P) cyberinfrastructure, advances permafrost community interests, and contributes valuable functionality and data to this necessary system. Specific project objectives are: 1) Aggregate, extract, pre-process, standardize, and reorganize data from beyond the GTN-P network in a cost-effective manner, increasing the breadth and depth of the GTN-P system by integrating valuable data holdings from the National Snow and Ice Data Center (NSIDC) Frozen Ground Data Center (FGDC) and Advanced Cooperative Arctic Data and Information Service (ACADIS) Gateway. 2) Extend semantic infrastructure by expanding the GTN-P ontology to include broader permafrost and climate modeling concepts and terms for data discovery, integration, and reuse. 3) Integrate GTN-P metadata and systems into the Arctic Data Explorer distributed search portal, and Arctic Observing Viewer data collection map to support federated data access. 4) Improve data usability by developing visualization services that quickly produce customized maps at multiple spatial scales to deliver information to researchers, citizen scientists, and policy makers.

科学驱动的网络基础设施：整合永久冻土数据、服务和研究应用程序该项目建议使用网络基础设施工具为科学界提供服务，以访问和发现选定的永久冻土数据集。监测地球气候的机构将永久冻土视为环境指标和基本气候变量。为了更好地了解其当前和过去的状态，有必要改进对永久冻土数据集（目前分散在网络上许多地方）的访问。全球科学和政策界需要全面、最新的永久冻土分布和状况地图。通过使永久冻土数据更易于使用，该项目支持目前每个实验室使用永久冻土数据重复的数据集成工作，并将通过释放关键时间进行独特的研究来推进知识的发展。项目成果对政策制定者、更广泛的科学研究人员、土著社区、基于社区的监测计划以及生活在永久冻土上或附近并研究永久冻土的其他人直接有用。通过科学驱动的网络基础设施，研究团队将提供一套可扩展的、多方面的服务，以解决永久冻土数据访问和可用性的复杂性。认识到这一领域协调努力的重要性，该项目将从之前的工作停止的地方开始。这项研究利用了国际永久冻土协会和全球陆地网络 - 永久冻土 (GTN-P) 网络基础设施的进展，促进永久冻土社区的利益，并为这个必要的系统贡献有价值的功能和数据。具体项目目标是： 1) 以经济高效的方式聚合、提取、预处理、标准化和重组来自 GTN-P 网络之外的数据，通过整合来自国家冰雪数据中心 (NSIDC) 冻土数据中心 (FGDC) 和高级合作北极数据和信息服务 (ACADIS) 网关的宝贵数据，增加 GTN-P 系统的广度和深度。 2) 通过扩展 GTN-P 本体来扩展语义基础设施，以包含更广泛的永久冻土和气候建模概念以及用于数据发现、集成和重用的术语。 3）将GTN-P元数据和系统集成到Arctic Data Explorer分布式搜索门户和Arctic Observing Viewer数据采集地图中，以支持联合数据访问。 4) 通过开发可视化服务来提高数据可用性，这些服务可以快速生成多个空间尺度的定制地图，从而向研究人员、公民科学家和政策制定者提供信息。
