Ionospheric behavior
Ionospheric behavior
Scintillations Occurrences• Recombination of electron density
• Equatorial Anomaly -> favorable to occur
• Geomagnetic Storms
• Earthquakes -> quick changes in geomagnetic field

Final Remarks
• Concentration of occurrence of ionospheric scintillation over the Equatorial Anomaly TAIL.
• It is hoped that the scintillations points follow the tail of the anomaly, but the distribution of stations CIGALA allows a dense analysis on part of region of Brazil.
It is just a begining...Search pattern among indices (TEC, ROT, ROTI, Kp, … )
Necessity to detecting Multipath combined with ISM
More analysis could be done with Ionospheric Profiles for Brazil and South America– Tomography Reconstruction of Ionosphere
