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

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 and Intercosmos-24 satellites. Results of the revised ion

Variability of the topside thermal plasma parameters during a period of high solar activity for IRI

The variability of the electron temperature, ion composition and the upper transition height in the topside ionosphere as given by the IRI models is studied. A variability index based on quartiles is introduced and...

New advances in empirical modelling of ion composition in the outer ionosphere

A new global empirical model of the relative ion composition in the outer ionosphere (altitude range of 500-2500 km) for the most important ions (O+, H+, He+ and N mission) by a Bennett ion mass spectromet...

Global characteristics of the upper transition height derived from the topside Alouette/ISIS topside sounder electron density profiles, the Formosat-3/COSMIC density profiles and the IRI ion

The upper transition height (Ht) (the altitude of the transition from heavy atomic ions to light ions or in the simplest form the transition from O+ to H+) is an important parameter, representing the boundary between the

Empirical modeling of the upper transition height for low and middle latitudes.

Ion composition data measured by the Bennett mass spectrometer during the ACTIVE mission (perigee 500 km, apogee 2500 km, maximum of solar cycle 22) and from AE satellites from the minimum of solar cycle 21 was used to study the sol...

Towards better description of solar activity variation in IRI topside ion composition model

/NOFS equatorial upper transition height (1000km vs 700km)showed a problem of the IRI ion composition model (both TTS03 and DY85) which were not constructed of the TTS03 model called TBTion model based on absolute ion

On possible improvements of outer ionosphere ion composition model in IRI.

The cuurent version of the IRI model for the ion composition and the electron (total ion) density above 500 km is compared with the Bennett ion spectrometer data measured in the frame of the ACTIVE mission (maximum...
