Abstract

Ionosphere is an atmospheric layer that has a high electron concentration and anisotropic, dispersive, inhomogeneous nature. Total Electron Content (TEC) is one of the most important parameters that provides necessary information to observe the ionospheric variability. In this study, spatial-temporal variability of the ionosphere is investigated using Symmetric Kullback Leibler Distance (SKLD), Metric Distance (L2N) and Cross Correlation Coefficient (CC) on Slant Total Electron Content (STEC) data provided by a midlatitude Global Positioning System (GPS) network. STEC data that are used are obtained by using IONOLAB-STEC method on Turkish National Permanent GPS Network Active (TNPGN-Active) stations during 2011 for quiet and disturbed days of ionosphere.
