    • Classification of regional ionospheric disturbance based on machine learning techniques 

      Terzi, Merve Begüm; Arıkan, Orhan; Karatay, S.; Arıkan, 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 ...
    • Investigation of hourly and daily patterns for lithosphere-ionosphere coupling before strong earthquakes 

      Karatay, S.; Arıkan F.; Arıkan, Orhan (IEEE, 2009-06)
      The ionosphere can be characterized with its electron density distribution which is a complex function of spatial and temporal variations, geomagnetic, solar and seismic activity. An important measurable quantity about the ...
    • Investigation of litosphere-ionosphere coupling using total electron content 

      Karatay, S.; Arıkan, F.; Arıkan, Orhan (IEEE, 2009)
      In this study, the relation between Total Electron Content (TEC) estimates obtained from GPS and the earthquakes is examined. Five earthquakes between 2003-2008 occured in Japan with different properties and China earthquake ...
    • Space weather studies of IONOLAB group 

      Arıkan, F.; Sezen, U.; Toker, C.; Artuner, H.; Bulu, G.; Demir, U.; Erdem, E.; Arıkan, Orhan; Tuna, Hakan; Gulyaeva, T. L.; Karatay, S.; Mosna, Z. (IEEE, 2016)
      IONOLAB is an interdisciplinary research group dedicated for handling the challenges of near earth environment on communication, positioning and remote sensing systems. IONOLAB group contributes to the space weather studies ...
    • A study of lithosphere-ionosphere coupling using TUSAGA active TEC estimates 

      Karatay, S.; Arikan F.; Arıkan, Orhan; Sayin I.; Aysezen, M.Ş.; Lenk O.; Aktuǧ, B. (IEEE, 2010)
      In this study, the disturbances in the ionosphere due to the seismic activity are investigated by using Total Electron Content estimates obtained from TUSAGA Active GPS stations in Turkey. Two earthquakes with same geophysical ...
