    Investigation of ionospheric trend over Turkey using sliding window statistical analysis method
    (IEEE, 2013) Deviren, M. N.; Arikan, F.; Arıkan, Orhan
    In this paper, variability of trend over Turkey is investigated statistically by Sliding Window Statistical Analysis (SWSA) method. First and second moment of the variability of ionospheric trend is calculated by SWSA method in a period of several years. Variance bounds are also obtained. This method is applied to Total Electron Content (TEC) estimates which are obtained from Turkish National Permanent GPS Network (TNPGNActive) between 2009 and 2012. The Wide Sense Stationarity (WSS) period of ionospheric trend over Turkey is determined for the first time. © 2013 IEEE.

    Investigation of short-period ionospheric variation over Turkey
    (IEEE, 2014) Deviren, M. N.; Arıkan, F.; Arıkan, Orhan
    In this paper, characteristic of short-period ionospheric variability over Turkey is determined statistically by a novel metric. First and second moment of the variability of ionospheric variations is calculated by Sliding Window Statistical Analysis (SWSA) method in 2011, and the ionospheric variations are investigated using this novel metric. Ionospheric storms will be characterized over Turkey and North Cyprus Turkish Republic between 2009 and 2013.
