Wrap up

• ESA's priorities
• Ionospheric characteristics affecting ESA
  missions (P-, C- and L-band)
• Long-term collection of ionospheric data,
  improved modelling of distribution of electron
  density, improved statistics of ionospheric
  conditions, linking of ionospheric conditions to
  system performance
• Ionospheric perturbations monitoring
• Customer oriented approach at DLT (SWACI service)
• Many products (perturbations, propagation of
  disturbances, TIDs,)
• Scintillation monitoring and modelling
• In the framework of COST 296 action
• Observations from high lat. to equatorial regions
• Scintillation data, statistics, models gt large
  share accessible via web portals

• To address key questions about the physics of the
  equatorial ionosphere
• Develop nowcast/forecasts capabilities on the
  onset of Spread F
