Coordinated Data Analysis Web (CDAWeb)

Public data from current and past space physics missions


NOTICE: As part of Federal policy to encrypt all network connections, FTP access to the SPDF and CDAWeb data archive is changing to TLS-encrypted FTPS on 2019 July 31. Browsers and traditional command line FTP will no longer connect with FTP, but HTTPS access remains. For more information and alternatives, see our FTPS Readme.

July 9, 2019: The THEMIS mission at Berkeley has reprocessed THEMIS FGM L2 files for probes A,D, and E 2018-07-01 on, and for probes B and C from 2017-03-01 on, with new calibration data. See the THEMIS Instrument processing history files for further details. All files have been re-ingested into the system..

June 21, 2019: All currently public Arase(ERG) and Van Allen Probes (RBSP) EFW L1 data sets have been added to the system. In addition, the TIMED Level-2A SABER data files have been reprocessed and ingested in to the system (V2.0 replaced by V2.7); see the TIMED SABER Level-2A release notes.

Per a US Government directive, the SPDF web sites and web services (CDAWeb, SSCWeb, OMNIWeb, etc.) are now using the HTTPS protocol, with only TLS 1.1 and TLS 1.2 connections allowed. Some web service clients (IDL 7, Java 6, etc.) will no longer be able to connect. FTP services will be changing to only allow TLS-based connections (FTPS, FTP-SSL) by the end of July, 2019.
