Abstract

Calculation of the influence of soft precipitating electrons on the polar ionosphere was carried out. The primary results are: (1) During summer time when the sunlight is the main source of upper atmosphere ionization, the additional soft electron precipitation can increase the N_mF₂. The daily variation of N_mF₂ is mainly controlled by solar EUV radiation. (2) At wintertime, when only soft electron precipitation ionization is considered f a peak at the height of F₂ layer also appears. The altitude profile of electron density is different from that when the sunlit ionization is taken into account.
