Abstract: | This work is devoted to a numerical simulation of the equatorial ionosphere, performed using the GSM TIP model completed with
a new block for calculating the electric field. It has been indicated that the usage of the wind system calculated according
to the MSIS-90 model makes it possible to reproduce the electromagnetic drift velocities at the equator, the effect of the
F2-layer stratification, and the appearance of the F3 layer in the equatorial ionosphere. The calculations performed using the modified GSM TIP model made it possible to detect
a maximum in the electron density vertical profile at an altitude of ∼1000 km, formed by H+ ions, which we called the G layer. If this layer actually exists, it can be observed during sounding the low-latitude ionosphere from satellites during
dark time of day. |
