  • The ionospheric kinetic numerical model is expressed as the solution to the temporal evolution of the electron density profile. The ion continuity and the momentum equations, the solar ionization, star ionization, coronal ionization, interstellar background ionization and meteor ion flow are all considered. The main kinetic process and photochemical process of Es layer are analyzed synthetically. The effects of neutral component collision, electric field, metal ion and molecular ion on the ion distribution are also included. In the paper, a one-dimensional time-dependent model of the ionospheric Es has been developed on the basis of the wind shear theory. The ion production rate and the distribution of the vertical ion velocity in height and time are simulated by the model. The variations of ion density profile in 24 hours are also obtained. According to the observation results of winds by coherent scattering radar in Kunming station, the time and space dependent of electron density of Es (Ne) is acquired by the model. Then the f0Es are given by the conversion of Ne, and the retrieval results are in good agreement with the contemporaneous ionosonde data in Kunming.
