“…The UAM successfully showed its ability to reproduce the general behavior of ionospheric and thermospheric parameters such as at low and high geomagnetic and solar activity conditions. A good agreement of the numerical simulations' results was achieved in comparison with observations by incoherent scatter radars located at various latitudes and longitudes (ISRs) [31], digital ionosonde CADI in the Voeykovo Main Geophysical Observatory [35], several chains of the ionospheric tomographical receivers [36][37][38], satellites, including CHAMP and GPS [3,4,26,30,[39][40][41][42], as well as with empirical models such as various types of IRI, MSIS, HWM [42][43][44][45][46][47], etc. and other theoretical models [42].…”
