    • Association of ionospheric storms and substorms of global electron content with proxy AE index 

      Yenen, S. D.; Gulyaeva, T. L.; Arikan, F.; Arikan, O. (Pergamon Press, 2015)
      Storm time modeling of Global Electron Content (GEC) calculated from GIM-TEC for 1999-2013 is associated with new proxy of Auroral Electrojet variability expressed as a smoothed and normalized Auroral Electrojet index ...
    • Classification of regional ionospheric disturbance based on machine learning techniques 

      Terzi, M. B.; Arikan, O.; Karatay S.; Arikan, F.; Gulyaeva T. (European Space Agency, 2016)
      In this study, Total Electron Content (TEC) estimated from GPS receivers is used to model the regional and local variability that differs from global activity along with solar and geomagnetic indices. For the automated ...

      Characterization and constant monitoring of variability of the ionosphere is of utmost importance for the performance improvement of HF communication, Satellite communication, navigation and guidance systems, Low Earth ...
    • Space-time interpolation and automatic mapping of TEC using TNPGN-active 

      Arikan F.; Arikan, O.; Sezen, U.; Toker C.; Aktug, B.; Lenk, O.; Kurt M.; Parmaksiz, E. (2011)
      Turkish National Permanent GPS Network (TNPGN) is the Reference Station Network of 146 continuously-operating GNSS stations o which are distributed uniformly across Turkey and North Cyprus Turkish Republic since May 2009. ...
    • Spatio-temporal interpolation of total electron content using a GPS network 

      Deviren, M. N.; Arıkan, F.; Arıkan, Orhan (IEEE, 2013)
      Constant monitoring and prediction of Space Weather events require investigation of the variability of total electron content (TEC), which is an observable feature of ionosphere using dual-frequency GPS receivers. Due to ...
