Total Electron Content and Electron Density Profile Observations during Geomagnetic Storms using COSMIC Satellite Data
Niraj Bhattarai, Narayan P Chapagain, Binod Adhikari
Total Electron Content (TEC) and electron density are the basic parameters, which determine the major properties of the Ionosphere. Detail study of the ionospheric TEC and electron density variations has been carried out during geomagnetic storms, with longitude and latitude, for four different locations: (24°W-14°W, 25°S-10°S); (53°W- 46°W, 04°N-14°N); (161°E-165°E, 42°S-34°S), and (135°W- 120°W, 39°S-35°S) using the COSMIC satellite data.In order to find the background conditions of the ionosphere.
