The habitability of planet Earth depends on a complex interaction between interior regions, solid surface, oceans, atmosphere, near-earth space environment, and Sun. Yet, study of this Sun-Earth system is traditionally broken up into separate geoscience disciplines, so that progress can be made by scientists working in reasonably-sized communities that share a common language and base of knowledge. To broach the bigger question of the interaction of the subsystems studied by the separate communities, it is necessary to overcome the barriers of communication posed by different observational instruments, software tools for interpreting data, and modeling methods. In answer to this challenge, the Integrated Geoscience Observatory is a pilot project that creates an online platform for integrating data and associated software tools contributed by separate geoscience research communities, into a unified toolset that brings them together. The vision is to expand the individual domains of geoscience research toward study of the whole Sun-Earth system, and in so doing to uncover the system level effects critical to the habitability of planet Earth.EarthCube aims to develop a framework for assisting researchers in understanding the Earth system. This systems science challenge is recognized in the Decadal Survey in Solar and Space Physics [2012], with the conclusion "Data from diverse space- and ground-based instruments need to be routinely combined in order to maximize their multi-scale potential." The Integrated Geoscience Observatory is a pilot project that explores realization of this vision by focusing on the limited context of geospace research. The observatory creates an integrated package of software tools contributed by researchers with specific capabilities, and designed to enable integration of diverse observational data. Features of the toolkit include: (A) linking diverse data sets from multiple data repositories and automatically mapping them to a common user-specified coordinate grid; (B) implementing the well-known Assimilative Mapping of Ionospheric Electrodynamics (AMIE) procedure for assimilation of this data to yield a global picture; and (C) utilization of the EarthCube building blocks GeoSoft, for communicating ontology, and GeoDataspace, for attributing credit to contributors through publication of processed data. The toolset can be accessed and used either through a web-based computing environment, or through download packages for local installation, with a nearly seamless transition between the two.

地球的宜居性取决于内部区域、固体表面、海洋、大气、近地空间环境和太阳之间的复杂相互作用。然而，对太阳-地球系统的研究传统上被分成几个独立的地球科学学科，这样科学家们就可以在共享共同语言和知识库的合理规模的社区中工作，取得进展。为了提出由不同社区研究的子系统之间的相互作用这一更大的问题，有必要克服不同观测仪器、用于解释数据的软件工具和建模方法造成的沟通障碍。作为对这一挑战的回应，综合地球科学观测站是一个试点项目，它创建了一个在线平台，将不同地球科学研究界提供的数据和相关软件工具整合成一个统一的工具包，将它们汇集在一起。其愿景是将地学研究的单个领域扩展到整个日地系统的研究，并通过这样做来揭示对地球宜居性至关重要的系统层面的影响。地球立方旨在开发一个框架，帮助研究人员了解地球系统。这一系统科学挑战在[2012]《太阳和空间物理十年调查》中得到承认，其结论是“来自各种天基和陆基仪器的数据需要定期合并，以便最大限度地发挥它们的多尺度潜力。”综合地球科学观测站是一个试点项目，它侧重于地球空间研究的有限背景，探索这一愿景的实现。天文台创建了一套集成的软件工具，由具有特定能力的研究人员贡献，旨在整合不同的观测数据。该工具包的特点包括：(A)将来自多个数据储存库的不同数据集连接起来，并自动将它们映射到一个共同的用户指定的坐标网格；(B)实施众所周知的电离层电动力学同化映射程序，以同化这些数据，以产生一幅全球图景；(C)利用地球立方体构建块Geosoft和GeoDatspace，通过发布处理后的数据，将信用归功于贡献者。该工具包可以通过基于Web的计算环境访问和使用，也可以通过本地安装的下载包访问和使用，两者之间几乎可以无缝过渡。
