SPDF

Space Physics Data Facility (SPDF) is the NASA active and permanent archive for non-solar heliophysics data (solar data at SDAC), per the NASA Heliophysics Science Data Management Policy. SPDF is a project of the Heliophysics Science Division (HSD) at NASA's Goddard Space Flight Center. SPDF also provides multi-project, cross-disciplinary access to data to enable correlative and collaborative research across discipline and mission boundaries with present and past missions. SPDF maintains 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.
