4. Conclusions
- (1)
- For seasonal variation, the foF2 in equinox months is greater than in solstice months. The average value of the foF2 in summer is the lowest value. However, the monthly average of the observed foF2 is the lowest in November, while it is in December for the IRI-2016.
- (2)
- Mostly, the IRI-2016 underestimated the foF2 compared with the observations in the present study. The IRI-2016 with the URSI performed a little better than the CCIR in prediction of the foF2.
- (3)
- The observed bite-out of foF2 in January and April occurred more frequently than other months and the IRI-2016 cannot represent the bite-out of foF2 in diurnal variations.
