Remarks
NASA’s Heliophysics Science Division at NASA HQs issued a revised Heliophysics Science Data Management Policy in 2009 (see https://hdrl.gsfc.nasa.gov/Heliophysics_Data_Policy_2009Apr12.html). This revised policy redefined the Heliophysics role of the NASA Space Science Data Coordinated Archive (NSSDCA) at Goddard to be solely that of a “deep archive” and defined a new role for the Space Physics Data Facility (SPDF)(https://www.re3data.org/repository/r3d100010168) to be one of two “active Final Archives” charged to work with NASA HQs to ensure the long-term accessibility and availability of all important NASA heliophysics data.
