JSOC SDP Scope
  • The HMI/AIA Joint SOC consists of two parts
  • Science Data Processing at Stanford
  • Science Instrument Operations at LMSAL
  • JSOC SDP includes
  • HMI and AIA Telemetry Data capture (from DDS) and
    archive
  • HMI and AIA Level-0 processing and archive
  • HMI processing through to level-2 with archiving
    of end products
  • AIA processing through level-1a with online
    storage
  • Data export of the above and other HMI and AIA
    products as needed
  • JSOC SDP does not include other Stanford tasks
    such as
  • HMI science analysis beyond level-2 products
  • HMI and AIA EPO
  • HMI Co-I science support
  • JSOC SDP does not include other LMSAL tasks such
    as
  • AIA level-1 and level-2 processing
  • AIA science analysis beyond level-2 products
  • AIA Co-I science support
