  • Empirical models of ionospheric parameters f0F2 and M(3000)F2 is obtained respectively by analyzing the observed data in Wuhan ionosphere Observatory. In these models, a linear function to describe the relationship between the two parameters and solar 10.7cm flux index is applied, and Fourier series analysis is used to investigate the diurnal and semidiurnal variations of f0F2 over Wuhan, and variations of M(3000)F2 from the first step to the fourth step. The agreement between the prediction and the observed data is satisfactory. Then the NmF2 and hmF2 can be modeled from f0F2 and M(3000)F2; And the oxygen scale height HO can be calculated using the modeled TEC and NmF2. Supposing that the height distribution of electron density fits Chapman α function, the Ne profile is given by inputting the modeled NmF2, hmF2 and HO. By integrating the profile with height in certain range, is estimated the partial electron content and compared with the observed TEC. The result suggests that the electron content integrated from 100km to 1000km are in agreement with the observed TEC at Wuhan. This method is useful for investigating the electron profile of F2 layer around the top, which has scarce observed data.
