| Abstract | This paper presents the performance of the latest version of the International Reference Ionosphere (IRI-2016) model for estimating the Total Electron Content (TEC) variations in the mid-latitudinal Turkish regions during low solar activity years (2015-2018). Moreover, TEC is estimated from dual-frequency Global Navigation Satellite System (GNSS) receivers operating in different regions of Turkey: Zonguldak (41.44 degrees N, 31.77 degrees E), Ankara (39.88 degrees N, 32.75 degrees E) and Antalya (36.88 degrees N, 30.66 degrees E). The diurnal, monthly and seasonal variations in the measured TEC are compared with the prediction of modelled TEC. The results reveal minimum variations in the diurnal TEC after midnight hours 21:00-24:00 Universal Time (UT=LT+3:00hrs) and maximum TEC enhancement during the daytime from 9:00-15:00 UT (12:00-18:00 LT). The monthly mean TEC from measured and modelled estimation depicts the highest and lowest values in April and December during the years 2015-2018, respectively. Moreover, the low and high seasonal variations are observed in equinoxes and winter solstice, respectively. Furthermore, it is observed that IRI-2016 model underestimates the measured values, especially during the daytime (12:00-18:00 LT) at each station. The correlation coefficient between the measured and modelled TEC is found in the range (R=0.81-0.85) during the years 2015-2018, which exhibits a high positive correlation over the regions. The model predicted TEC is showing a good agreement with measured TEC of the ionospheric dynamics over the regions, which manifests the radio signals accuracy over the mid-latitude regions, particularly Turkey. |
