This study presents the modeling of ionospheric response
to geomagnetic storms of September 9-14, 2005. We examine the
performance of the Global Self-Consistent Model of Thermosphere,
Ionosphere and Protonosphere (GSM TIP) and International Reference
Ionosphere-2000 (IRI-2000), and compare the modeling predictions
with the ionosonde and incoherent scatter radar observations over
Yakutsk, Irkutsk, Millstone Hill and Arecibo stations. IRI-2000
predicted well all negative foF2 disturbances. In comparison with
IRI-2000, the GSM TIP better reproduced the positive phase observed
during the disturbed times. We discuss the possible reasons of the
differences between the GSM TIP model calculations, IRI
predictions, and the observations.
Key words: Ionospheric storm, foF2 disturbances, thermospheric wind, neutral atmosphere composition, electric field, numerical modeling, IRI model.
