PROJECT
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
SERVICES
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)
