ESA Pilot project to extend the Space Weather community in Europe

CLS proposal for a ionospheric scintillation monitoring service:

  • a strong influence on radio-propagation signals (large range of human activities)
  • a few knowledge of the effects (geomagnetic equator, after sunset...)
  • the GPS/GLONASS permanent network opportunity for a global near real time observing system (effects)

  • European consortium with representative users
  • ESA conditions: near real-time operational part of the Service is Public


User needs for a Public Service

  • Global maps of the nowcast status of the ionospheric scintillations.
    The main need for a Public Service is to have the answer to the questions: where are the scintillations occuring and what are their intensity?
  • Dedicated data bank.
  Public service

Global maps of scintillations of presumed effects:
- 1 hour refreshment
- Day/night activity

Web interface including general and technical presentation
  Specific analysis:

- Budget links for an orbiting receiver
- Regional monitoring, alarms
- Occurrence characterization (versus local time, geomagnetic location, solar and geomagnetic activities)
