Updates on Nigerian Space Science Data System Presentation by ESTHER HANSON Eduok @ Pre-ICRI Workshop, ICC, Cape Town, South Africa 10/02/2016

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. Fig 1: Hourly variation of radio wave amplitudes. Presentation by ESTHER HANSON Eduok @ Pre-ICRI Workshop, ICC, Cape Town, South Africa 10/02/2016

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 (2005-09) & ISWI (2009-present) to identify host nation partners & collaborators. Presentation by ESTHER HANSON Eduok @ Pre-ICRI Workshop, ICC, Cape Town, South Africa 10/02/2016

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).
