Abstract
In this paper the formulation of the problem and preliminary numerical computation results of the thermosphere-ionosphere-protonosphere system parameters are discussed.
The model constructed describes time-dependent distributions of the multicomponent near-earth space plasma parameters by means of numerical integration of the appropriate three-dimensional plasma hydrodynamic equations. In the thermospheric block of the model, global distribution of neutral gas temperature and N2, O2, O concentrations, as well as three-dimensional circulation of the neutral gas are calculated in the range of height from 80 km to 520 km. In the ionospheric section of the model, global time-dependent distribution of ion and electron temperatures, as well as molecular and atomic O+, H+ ion concentrations are calculated. Global two-dimensional distribution of electric potential is calculated taking into account computed thermosphere and ionosphere parameters.
The inputs needed for our global model are the solar EUV spectrum; the auroral precipitation pattern; the distribution of the field-aligned currents and the model of the geomagnetic field.
Preliminary results are obtained without regard to electromagnetic plasma drift for the solar minimum, low geomagnetic activity and spring equinox conditions. Global distributions of the calculated parameters in the magnetic dipole latitude-longitude frame are presented for 1200 UT. In the summary ignored processes and future direction are discussed.
