A modelling study of Indian low latitude ionosphere—Part II: Results and comparison with SROSS-C2 satellite data

Abstract

A time-dependent model developed for the Indian low latitude ionosphere (Part l) is used to calculate the O⁺ and H⁺ ion density distribution within ± 15° geomagnetic latitude. The calculations are performed along magnetic field lines from a base altitude of 120 km in the northern hemisphere to the same altitude in the southern hemisphere for solar minimum equinoctial conditions. It is found that the modelled O⁺ and H⁺ concentrations are in reasonable accord with the observations made from Indian SROSS-C2 satellite at a height of ~500 km over India during the period August 1995-July 1996.
