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: September 2022: GOES magnetometer (MAG) high-resolution data is now available in CDAWeb for GOES-08 to GOES-17, covering the period between 1995 and present. The GOES MAG subsystem consists of fluxgate magnetometer instruments monitoring three orthogonal components of the geomagnetic field at geosynchronous orbit (L = 6.6) with high-resolution sampling rate (G8-15: 2 Hz and G16-17: 10 Hz).

August 2022: The PSP data have been extended up to April 2022, covering the rest of Orbit 11 and part of the inbound leg of Orbit 12. Two new FIELDS datasets are added. They are Level 2 Antenna Electronics Board (AEB) data and Level 3 Simplified Quasi-Thermal Noise (SQTN) data using the Radio Frequency Spectrometer (RFS) spectra. Pitch angles are included in the ISOIS datasets whenever FIELDS data are available. EPI-Lo calibrations have been updated for apertures with thick entrance foils.

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.
