Comparison between the ionosonde and Himawari-8 satellite observations. (a) Time-series plot of h’F variation at a frequency of 4 MHz at Wake. (b) Geographic latitude time plot of temperature deviation (d3) aligned with the geographic longitude of 166.64°E observed by the Himawari 8 satellite during 04:00–12:00 UTC on January 15, 2022. The vertical dotted line in panel (a) reflects the sunset terminator of the E region height of 105 km. The horizontal dashed line in panel (b) is the geographic latitude of the Wake station.
