Public data from current and past space physics missions

August 1, 2019: As part of Federal policy to encrypt all network connections, FTP access to the SPDF and CDAWeb data archive changed to TLS-encrypted FTPS on July 31, 2019. 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.

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 changed to only allow TLS-based connections (FTPS, FTP-SSL) on July 31, 2019.
