Global modelling study (GSM TIP) of the ionospheric effects of excited N 2 , convection and heat fluxes by comparison with EISCAT and satellite data for 31 July 1990
Near-earth plasma parameters were calculated using a global numerical self-consistent and time-dependent model of the thermosphere, ionosphere and protonosphere (GSM TIP). The model results are compared with experimental data of different origin, mainly EISCAT measurements and simultaneous satellite...
