ZCB Space Physics Data Facility (SPDF) is the NASA active and permanent archive for non-solar heliophysics data per the NASA Heliophysics Science Data Management Policy. SPDF is a project of the Heliophysics Science Division (HSD) at the NASA Goddard Space Flight Center. SPDF also provides multi-project, cross-disciplinary access to data to enable correlative and collaborative research across discipline and mission boundaries with present and past missions. Many datasets from current missions are updated regularly (even daily), including reprocessing older time periods, and SPDF only preserves the latest version. SPDF maintains the Satellite Situation Center (SSCweb) database of spacecraft orbits, the OMNIweb Plus cross-normalized database, and the Common Data Format (CDF) self-describing science data format and associated software. Solar data is available from the Solar Data Analysis Center (SDAC). spase://SMWG/Person/Robert.M.Candey ProjectScientist 2019-08-01T00:00:00 spase://SMWG/Person/Robert.E.McGuire ProjectScientist 2019-08-01T00:00:00 spase://SMWG/Person/Lan.Jian DeputyPI 2019-03-20T00:00:00 spase://SMWG/Person/Tamara.J.Kovalick GeneralContact spase://SMWG/Person/Robert.M.Candey TechnicalContact SPDF Home Page https://spdf.gsfc.nasa.gov/ Space Physics Data Facility Home Page of the NASA Goddard Space Flight Center spase://vspo/repository/61 spase://SMWG/Repository/SPDF Access to SPDF Data https://spdf.gsfc.nasa.gov/ 00ryjtt64
