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. Many datasets from current missions are updated regularly (even daily), including reprocessing older time periods, and SPDF only preserves the latest version. 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.

News & Announcements

NOTICE: November 2022: The PSP data have been extended up to August 2022, covering the rest of Orbit 12 and part of the inbound leg of Orbit 13. EPI-Lo calculations have been updated affecting Quadrant 1 (look directions 20-39) fluxes and count rates. Please check the PSP inventory plot and annual inventory plots for details.

March, 2022: A new CDF version 3.8.1 distribution is now available. See the CDF home page for links to the software/documentation and the 3.8.1 Release Notes.

March, 2022: A total of 17 Level 2 Solar Wind Analyser (SWA) datasets from the Solar Orbiter mission have been added to CDAWeb.

The MMS Level 2 data products are available via SPDF HTTPS and all data sets are available in CDAWeb. The range of publicly available MMS data will continue to be updated weekly.
