Coordinated Data Analysis Web (CDAWeb)

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...

April 16, 2024: All SPDF web services for CDAWeb and SSCWeb will be unavailable from 10am - 10:30am EDT on Tuesday, 4/16/2024. Please plan your use of the services accordingly.

February 2024: Mars Global Surveyor (MGS) magnetometer data and Mars Science Laboratory (MSL) radiation data for many years have been added to the system, services and archive.

January 2024: A new plotting option has been added to allow auto-scaling by time (the default is to not autoscale time, but rather to show the time range requested). This option should allow users to more easily navigate burst data.
