3. Introduction Data Sharing?
Making research data available to other investigators.
Data Re-use???
To use data that is considered past its usefulness, again.

6. Ionospheric Scintillation Activity in Africa unknown!
Scintillation: Rapid amplitude and phase fluctuation of radio signals in space due to turbulence.
Scintillation affects radio signal up to few GHz frequency; seriously degrading and disrupting satellite-based navigation and communication systems.

7. SCINDA
SCINDA: Scintillation Network Decision Aid. Real-time, data-driven communication outage forecast and alert system hosted by AFRL, USA.
SCINDA was designed to provide regional specification and short-term forecasts to operational users in real-time.
SCINDA worked with IHY ( ) & ISWI (2009-present) to identify host nation partners & collaborators.

8. Equatorial Scintillation Sites
Network Coverage: Equatorial Stations in South America, Southwest Asia and Southeast Asia.
Scintillation activity across Africa assumed high based on satellite observations, but ground-based measurements are needed (Groves et al., 2012).
