| Özet |
| Electron density is the basis parameter in the ionosphere. Anormally decreasing or increasing of electron density cause disturbances/anomalies in ionosphere. Electron density distribution varies depending on geographic location, seasons, altitude, solar, geomagnetic and seismic activities. Detecting of these disturbances are important for propagation of the radio signals which are used by space based communication, positioning and navigation systems. Travelling ionospheric disturbances (TIDs) are wave-like perturbations of the ionospheric plasma. They can be classified according to their frequency, duration and amplitude as Medium Scale Travelling Ionospheric Disturbances (MSTIDs) and Large Scale Travelling Ionospheric Disturbances (LSTIDs). These disturbances are easily detected analyzing Total Electron Content (TEC) data. TEC is proportional to the total number of electrons on a path crossing the atmosphere. TEC measurements are obtained by Global Positioning System (GPS). In this study, a new method is developed, namely is Differential Rate of TEC (DRoT), for investigating the disturbances in ionosphere. DRoT is the normalized metric norm between the RoT and its baseband trend structure. The effects of geomagnetic and seismic activities to the ionosphere in the midlattitude and equatorial region are analyzed. If DRoT value is lower than 50%, there are no significant disturbances. If DRoT value is between 50% and 70%, MSTIDs are observed. If DRoT value is higher than 70%, LSTIDs are observed. |
