The Hinotori satellite observed the electron density and temperature around the equatorial anomaly region at ∼600 km altitude during high solar activity. The observed electron temperature in the equatorial F region ionosphere was compared with the International Reference Ionosphere (IRI) model. The results showed the large difference between observation and model. Time dependent three dimensional computer simulations of the equatorial ionospheric F region have been carried out to investigate the electron temperature anomaly. These simulations coincide with the equatorial electron density and temperature structure observed by the Hinotori satellite.
