NSSDC is a partner of Goddard's
Solar Data Analysis Center
(SDAC) in the archiving and dissemination of data from NASA and some other
solar missions. The SDAC is the active archive, providing network access to
data from such missions as SOHO, Yohkoh, and TRACE. NSSDC typically provides
for the permanent archiving of these data and high-volume offline dissemination.
The NSSDC Flight Projects page has
information about currently important solar missions and their data.
