Abstract:

The flow of thermal energy through the electron gas of the ionosphere in response to gradients in electron temperature plays an important part in determining the actual electron temperature profile. In this paper it is shown that the neutral atmosphere can significantly reduce the electron thermal conductivity by decreasing the electron mean free path below these distances typical of a fully ionized gas. A basic equation for the thermal conductivity is developed and several examples are given of its application. It is shown that for typical atmospheric conditions there is essentially no heat conduction below 150 km while significant reductions must exist to at least 200 km. Author
