Response of Ionospheric Total Electron Content to Convective Vortices

详细

The response of the total electron content (TEC) of Earth’s ionosphere to impulse geomagnetic disturbances, traveling convection vortices (TCVs), is considered in the paper. The data of networks of ground-based magnetometers in Canada and Greenland were used to reveal TCVs, whereas the TEC variations were obtained by processing the data of the IGS and UNAVCO receiving stations of the global positioning system (GPS). Ionospheric disturbances related to TCVs are detected. Using the station network makes it possible to estimate the dynamics of formation and velocity of propagation of the disturbance in space.
