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.
News & Announcements
NOTICE: November 18, 2020: The Parker Solar Probe (PSP) data has been extended through August 2020, for most data sets, and includes encounter 5 and the remainder of orbit 5. The new data files were added to the CDAWeb system and to the SPDF PSP archive.
NOTICE: November 11, 2020: The insitu and ephemeris data from the Solar Orbiter mission are available at the SPDF Solar Orbiter archive. The Level 2 and above of science data as well as the low latency data are served at CDAWeb. All the data are mirrored from the ESA Solar Orbiter Archive.
NOTICE: July 2020: SPDF WEB ADDRESS CHANGES: Alternate names for the web addresses for various SPDF web sites have been deprecated and redirected to the standard name. For instance, please change any use of spdf.sci.gsfc.nasa.gov to https://spdf.gsfc.nasa.gov/ and cdaweb.sci.gsfc.nasa.gov to https://cdaweb.gsfc.nasa.gov/.
NOTICE: 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.
New CDF Version 3.8.0 Released
Common Data Format (CDF) Version 3.8.0 is now available. Updates for Perl, IDL, Matlab, and Java interfaces and the SKTeditor CDF editor are available. For further details and changes, see the CDF release notes.
