Abstract

Electron density N(h)-profile is important geophysical characteristic and is the aim of many radiophysical methods of upper atmosphere investigation. The work is devoted to comparative analysis of the four different methods of electron density reconstruction from vertical sounding (vertical-incidence) data. The digisondes make good use of the Huang-Reinisch method for N(h)-profile reconstruction from measured vertical sounding data. The Guliaeva technique of N(h)- profile reconstruction is also widely distributed in the science environment. But this technique asks for complete height-frequency characteristic. And calculation of the peak height of the F2-layer in critical frequencies region requires the very small frequency step. The Mikhailov method (reducing this disadvantage in hmF2 calculation) was examined too. Among other things, the N(h)-profile reconstruction can be carried out via capability of the International Reference Ionosphere model to adapt by parameters which can be received from measured height-frequency characteristic. In the work comparison of the mentioned methods of N(h)-profile reconstruction was carried out on the basis of vertical sounding data obtained by DPS-4 Digisonde in Irkutsk in 2006.
