Description
Summary: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 NmF2. The daily variation of NmF2 is mainly controlled by solar EUV radiation. (2) At wintertime, when only soft electron precipitation ionization is considered, 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.
