CDAWeb contains selected public non-solar heliophysics data from current heliophysics missions and projects. Many datasets from current missions are updated regularly/daily, including reprocessing older time periods, and SPDF only preserves the latest version. To find all of the public data and documents archived by the SPDF, see the SPDF archive. To search for additional heliophysics data products, check the heliophysics data portal.

REMINDER: CDAWeb offers CREATION of subset/supersets of data sets (by date and variables), CREATION of uniformly time binned data, PLOTS in PDF, PS and PNG formatted files, MOVIES of specific image sequences, ON-THE-FLY Inventory plots, ADJUSTABLE height time/spectrogram plots, plus many more options...

December 2025: New data files for more than 100 datasets of THEMIS ground-based magnetometers are available at the SPDF archive. The magnetic field coordinate system labels are changed from "HDZ" to "HEZ" to better reflect data vector components. The DOI attribute is added to metadata for all stations where available. SPDF staff are working on adding the datasets to the system.

December 2025: The STEREO mission has made a new version of merged 1-min plasma and magnetic field data for STEREO A and B. The spacecraft position data in RTN coordinates are replaced with the one in Heliocentric Inertial (HCI) coordinates.

December 2025: The PSP data have been extended to August 2025 (availability depending on the datasets), covering Encounter 24 with the closest approach to the Sun in June 2025. Nine Energetic Particle Instrument (EPI) datasets of ISOIS instrument suite are changed with new electron and heavy ion fluxes (details in the ISOIS release note). Please check the PSP inventory plot and the annual inventory plots for time coverage of various data sets.
