Coordinated Data Analysis Web (CDAWeb)

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...

November 2023: The PSP data have been extended to August 2023 (availability depending on data sets), covering Encounter 16 and some of Orbit 16. Please check the system, the PSP inventory plot and the annual inventory plots for details.

October 2023: The PSP data have been extended to June 2023, covering the rest of Orbit 15, including Encounter 15, and part of the inbound leg of Orbit 16. New Radio Frequency Spectrometer (RFS) Level 3 High Frequency Receiver (HFR) and Low Frequency Receiver (LFR) data sets from the FIELDS instrument suite were added.

September 2023: New Cluster CIS data have been added to the system - 198 Ion Spectrometry (CIS) data sets are available in the system and the SPDF archive.
