The SPDF is a project of the Heliospheric Science Division (HSD) at NASA's Goddard Space Flight Center. SPDF consists of web-based services for survey and high resolution data and trajectories. The Facility supports data from most NASA Heliophysics missions to promote correlative and collaborative research across discipline and mission boundaries. Read More here.
On September 24 and 25, the Space Physics Data Facility (SPDF) renamed and restructured its FTP and HTTP accessible directories. This newly unified structure merges CDAWeb files already served by SPDF with legacy heliophysics data holdings that have been served by the National Space Science Data Center (NSSDC) on http://nssdcftp.gsfc.nasa.gov. The responsibility for the final archiving of heliophysics has been transferred from NSSDC to SPDF (for non-solar instruments) and to Solar Data Analysis Center (SDAC) (for solar instruments). SPDF will also serve legacy solar instrument data previously served by NSSDC on at least an interim basis.
All heliophysics data and other files previously accessible separately from NSSDCftp or CDAWeb are accessible from any of the addresses
ftp://spdf.gsfc.nasa.gov/pub,
http://spdf.gsfc.nasa.gov/pub,
ftp://cdaweb.gsfc.nasa.gov/pub,
http://cdaweb.gsfc.nasa.gov/pub.
Other SPDF services are unchanged. Read More...
SPDF is concerned that important data from older missions (past and current) are at increasing risk of being lost as projects and their funding expire, and as the scientists responsible for the data move to new missions, change responsibilities or retire. If you have or know of existing heliophysics data that may not yet be safely archived, please contact SPDF. Read More...
