NASA's Space Physics Data Facility (SPDF)

Heliophysics studies the nature and dynamic interactions of the Sun, the heliosphere, and the plasma environments of the planets and interstellar space. The Heliophysics Digital Resource Library (HDRL) archives and serves the heliophysics data, as a project in the Heliophysics Science Division (HSD) at NASA's Goddard Space Flight Center. Space Physics Data Facility (SPDF) is the active and permanent archive for the space physics data, while solar data is archived at Solar Data Analysis Center (SDAC), as components of the HDRL, per NASA’s Heliophysics Science Data Management Policy. Visit NASA Heliophysics Data for more information, policy, and document templates.

SPDF provides multi-project, cross-disciplinary access to data to enable correlative and collaborative research across discipline and mission boundaries with present and past missions. Many datasets from current missions are updated regularly (even daily), including reprocessed data for older time periods, and SPDF only preserves the latest version. SPDF maintains the CDAWeb data explorer and browsing system, the SSCweb database of spacecraft orbits, the OMNIWeb cross-normalized database, and the Common Data Format (CDF) self-describing science data format and associated software.
