Effects of the precipitation electrons on the polar ionosphere with different energy spectrum

This paper calculated the height-integrated conductance and the electron density in the F-layer of the polar ionosphere, based on one self-consistent model of the polar ionosphere, which takes the ionization of the precipitation electrons with different energy spectrum into account. It is found that the energy spectrum of the electrons doesn't have an obvious effect on the conductance. The average energy of the electrons is the determinant factor of the conductance. The relative magnitude of the conductance deduced using the different energy spectrum of the electrons also depends on the average energy. On the other hand, the electron density in the F-layer is well affected by the energy spectrum of the precipitation electrons. The larger the average energy of the precipitation is, the more notable the effect is.
