The resulting dawn-to-dusk electric field maps down to thermospheric heights, where it causes the ionospheric ions to drift in an E×B direction and, through collisions with the neutral gas, affects neutral dynamics. To model the thermosphere one needs to consider the complex interactions between neutral and plasma dynamics and electrodynamics.
The thermosphere is the layer in the Earth's atmosphere directly above the mesosphere and below the exosphere. Within this layer of the atmosphere, ultraviolet radiation causes photoionization /photodissociation of molecules, creating ions; the thermosphere thus constitutes the larger part of the ionosphere.
The thermosphere is defined as the second-highest layer of the Earth's atmosphere, extending from the mesopause to the thermopause, characterized by high temperatures influenced by solar activity and molecular diffusion leading to gravitational separation of species.

The thermosphere is that rarefied portion of a planetary atmosphere which extends from the top of the middle atmosphere (mesosphere) to the beginning of outer space (exosphere; Figure T15).
22 kwi 2021 · Definition. The region of an atmosphere called the thermosphere is characterized by an increase in neutral temperature as a function of altitude and asymptotes to a relatively constant temperature. The corresponding neutral atmospheric density is decreasing with altitude.
The thermosphere is a layer of Earth's atmosphere that is directly above the mesosphere and below the exosphere. It extends from about 90 km (56 miles) to between 500 and 1,000 km (311 to 621 miles) above Earth's surface.
The thermosphere is a layer of the Earth's atmosphere that extends from 100 km to around 1000 km. It is characterized by high atmospheric temperature and is influenced by variations in solar extreme ultraviolet radiation and geomagnetic activity.
