摘要

Near-earth plasma parameters were calculatedusing a global numerical self-consistent and time-dependent model of thethermosphere, ionosphere and protonosphere (GSM TIP). The model results arecompared with experimental data of different origin, mainly EISCAT measurementsand simultaneous satellite data (Ne and ion composition).Model runs with varying inputs of auroral FAC distributions, temperature ofvibrationally excited nitrogen and photoelectron energy escape fluxes are usedto make adjustments to the observations. The satellite data are obtained onboardActive and its subsatellite Magion-2 when they passed nearby the EISCAT stationaround 0325 and 1540 UT on 31 July 1990 at a height of about 2000 and 2200 km,respectively. A strong geomagnetic disturbance was observed two days before theperiod under study. Numerical calculations were performed with consideration ofvibrationally excited nitrogen molecules for high solar-activity conditions. Theresults show good agreement between the incoherent-scatter radar measurements (Ne,Te, Ti) and model calculations, taking intoaccount the excited molecular nitrogen reaction rates. The comparison of modelresults of the thermospheric neutral wind shows finally a good agreement withthe HWM93 empirical wind model.
