Abstract

The behavior of correlation coefficients for long-period wave disturbances (periods more than 24 hours) of the F2-layer peak electron density (NmF2) and the ionospheric total electron content (TEC) at different levels of solar and geomagnetic activity in 2003-2020 was studied. The study was based on the data from the vertical sounding ionosonde and GNSS receiver located at Irkutsk. It is shown that correlations between long-period variations in TEC and NmF2 are higher in the daytime than at night, at high solar activity compared to low, and in winter compared to summer. These differences may be caused by different contributions of the ionospheric and plasmaspheric electron content to TEC and/or synchronization of TEC and NmF2 changes by short-term (for example, 27-day) changes in solar activity.
