Comparison between the TEC, ionosonde, and Himawari-8 satellite observations. (a–c) Time-series plots of TEC, ROT, and ROTI at GUUG obtained from PRN16 (corresponding to the GPS satellite number). (d) Time-series plots of h’F at a frequency of 4 MHz observed by the ionosonde in Guam. The black dashed lines in each panel (a–d) indicate the values of each parameter during 04:00–12:00 UTC on January 13, 2022. (e) Geographic latitude-time plot of Himawari-8 temperature deviation (d3). The horizontal dashed line represents the ___location of the ionosonde at the Guam station. The geographic longitude and latitude shown in the bottom panel (e) indicate the ionospheric pierce point at a height of 300 km between the GUUG station and PRN16.
