  • Introduction and Overview The goal of the Heliophysics Data Environment, defined as the collective set of data from the “Heliophysics System Observatory” fleet and related resources, is to enable science discovery. The Data Environment provides essential infrastructure supporting NASA’s Vision to understand “the Sun, the Heliosphere, and planetary environments as elements of a single interconnected system, one that contains dynamic space weather and evolves in response to solar, planetary, and interstellar conditions” [NASA Sun-Solar System Connection Science and Technology Roadmap 2005-2035]. We have a rich set of data, but it is in a wide variety of places and formats, and available though a varied collection of interfaces. This proposal offers a plan to provide the right lightweight infrastructure to support the uniform discovery, access, and use of a comprehensive set of space and solar physics data resources. We want to make obtaining a useable form of the necessary data the easiest part of any Heliophysics science exploration task. New science is enabled when much more time can be devoted to analysis than to data discovery and preparation. Using new datasets should be a matter of browsing and understanding their content; too often we never get to that point because the data are difficult to read or lack basic documentation. We propose to make such difficulties a thing of the past for Heliophysics. Our key concept is that of integration: bringing together diverse things and making them useful with each other. The goal of integration will be enabled by ongoing support for the upgrading, serving, and preserving of data products; the provision of browser and computer interfaces for "one-stop shopping" for data based on uniform terminology; the completion and maintenance of a comprehensive product inventory; and the development of basic services that allow the user to browse and use any datasets. Integration includes the idea of standardization through the use of uniform descriptions for spacecraft, observatories, instruments and data. It includes the idea of advanced searches that locate and gather data (or pointers to data) from many distributed providers, and it means simplifying or enhancing interfaces to many providers and making their data searchable with one interface. Integration includes providing tools that will allow the use of diversely formatted data, making it easy to perform side-by-side comparisons of diverse, distributed data products. We want to make various seemingly simple tasks, such as comparing two or more related science measurements, actually simple to execute. Ultimately, integration means developing standard tools for mapping between data sets in different regions of the nonlinear dynamical Sun-Earth and Sun-Planetary environments that are the domain of Heliophysics. The resulting global views cannot help but trigger new types of questions and new ways of doing science enabled by the Heliophysics Data Environment. The Heliophysics Data and Model Consortium (HDMC) was initiated on October 1, 2008 to formalize this integration as part of the overall Heliophysics infrastructure. While formally a NASA organization, with specific NASA-funded elements that are being reviewed here, this consortium is international since the data needed for space physics research are distributed around the world. The HDMC was built on a number of years of gr
