Özet
This paper investigates the performance of International Reference Ionosphere (IRI-2016) in predicting the variation of the Total Electron Content (TEC) over six IGS stations in the mid-latitude region. Three of the stations are in the northern hemisphere and three in the southern hemisphere. IRI-2016 TEC values are estimated using various Ne Topside, Ne F-peak and F-peak height options during different geomagnetic and solar activity conditions. Three different ionospheric conditions are considered; geomagnetic active-solar quiet days (June 23, 2015; October 7, 2015), geomagnetic-solar quiet days (May 23, 2015; July 19, 2015) and geomagnetic quiet-solar active days (July 8, 2014; December 18, 2014). Model derived TEC values are compared with the GPS-TEC data, which is used as a reference value. The overall results show that TEC predictions using IRI-2001 (Ne-Topside) and URSI (Ne F-peak) options provide better agreement with GPS-TEC values for the summer days. Whereas IRI01-corr-NeQuick (Ne-Topside) with CCIR (Ne F-peak) options predict well for the winter days. Besides, evaluation of the results reveals insignificant differences (<1 TECU) among three F-peak height option (AMTB-2013, SHU-2015 and BSE-1979) solutions. Furthermore, regardless of which IRI parameter is used during active days, the differences between IRI-TEC and GPS-TEC reach high values at some stations at some time intervals.
