Towards better description of solar activity variation in the International Reference Ionosphere topside ion composition model

Popis výsledku v původním jazyce

We present a revision of the ion composition model that is included in the International Reference Ionosphere (IRI) as the TTS-03 option. We employed a better description of the solar activity variation based on the assumption that the dependence of thelogarithm of absolute densities of the individual ion species (H+, O+, He+ and N+) on the F10.7 index is linear. Unlike the TTS-03 model using the relative ion densities, the revised model employs absolute ion densities measured by the Atmosphere Explorer C&E and Intercosmos-24 satellites. Results of the revised ion composition model are presented, with special emphasis on the upper transition height (HT) during low solar activity. Equatorial HT produced by the model for a very low solar activity is 800km at daytime (14 h LT) and 520 km at nighttime (2 h LT). These values are closer to HT observed by the Coupled Ion-Neutral Dynamics Investigations (CINDI) on the Communications/Navigation Outage Forecasting System (C/NOFS) satellite in
