Specification of electron density and temperature in the ISO_IRI ionosphere-plasmasphere model
Abstract
Technical Specification TS16457 of the Earth's environment model for density, temperature and effective collision frequency of electrons in the ionosphere and plasmasphere is a project of the International Organization for Standardization, ISO. The ISO_IRI code (ftp://ftp.izmiran.rssi.ru/pub/izmiran/SPIM/) is based on the International Reference Ionosphere electron density extended towards the plasmapause (up to 35,000 km) with Russian plasmasphere model. The IRI topside ionosphere model (Bent, 1972) is improved with the half-width model of topside electron density (Gulyaeva, 2004) deduced from the topside sounder data onboard the ISIS1, ISIS2, and IK19 satellites. Extension of IRI ionospheric electron temperature towards the plasmasphere is investigated using the Akebono-based Te model above the IRI reference height of 1400 km to 10000 km (Kutiev et al., 2002) Results are compared with the electron temperature model for the upper ionosphere and plasmasphere (Titheridge, 1998) including dependence on solar and magnetic activity. More extensive validations of the ISO_IRI code with independent models and data sources are required for making final recommendation by ISO.
