Abstract:

Data in different longitude sectors were examined to investigate the influence of Equatorial Electrojet (EEJ) on the Global Positioning System (GPS)-TEC in the South American continent. Our findings from this comparative study demonstrate that EEJ is weaker on the eastern side and gradually becomes stronger towards western side of South America. We also observed that EEJ strengths have some influence on the shape, size, amplitude and separation of Equatorial Ionization Anomaly (EIA) crests as seen through ionospheric TEC distribution measured using GPS.
