CDAWeb contains selected public non-solar heliophysics data from current and past heliophysics missions and projects. Many datasets from current missions are updated regularly (even 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...

March 9, 2026: Temporary and Intermittent Outages at the NASA Space Physics Data Facility (SPDF) and Solar Data Analysis Center (SDAC) Services:

The services of the NASA Space Physics Data Facility (SPDF) and Solar Data Analysis Center (SDAC) will be offline for at least one day in March while the primary servers are moved to another building at NASA Goddard Space Flight Center (GSFC). The tentative move date is March 9 but could slip. Main affected services include Coordinated Data Analysis Web (CDAWeb), Satellite Situation Center Web (SSCWeb), OMNIWeb, Virtual Solar Observatory (VSO), Helioviewer, and the associated Application Programming Interfaces (APIs). In the days following March 9 users should expect temporary and intermittent interruptions to services as they come back online.
