The Equatorial Ionization Anomaly (EIA) region, which comprises of almost two-thirds of the density of global TEC, has crests at around ±30 about the magnetic equator. Indore falls near to the northern anomaly crest and as a result sharp latitudinal gradient exists in and around this region. Hence analysis of TEC over this region becomes very necessary to characterize the equatorial ionosphere. It is also well known that TEC is strongly affected by solar activity and any enhancement in the ionospheric TEC due to the influence of this solar activity may cause dramatic increase in the pseudo-range error. In the present work, TEC over Indore has been analyzed using a dedicated python pipeline, as huge amount of data handling is necessary for such time series analysis during the present low activity phase of the Sun. Observations have been made when there had been disturbances due to geomagnetic storms during this period |
