英文摘要	The ionospheric behavior during magnetic storms is an important research topic in ionospheric physics. In this paper, the ionospheric observations from the 31-days Millstone Hill incoherent scatter radar and GPS satellites are used to study the ionospheric responses of electron density at different altitudes during the magnetic storm events on October 13-17 and 22-26, 2002. The results show that the absolute changes in electron density versus the heights are the same for both positive and negative phase storms, however, time, phase and magnitude of responses are inconsistent with each other at different heights; The height of the maximum absolute change of the negative phase storm is highly consistent with the non-storm F-2 layer height, which has a good correlation between them, while the positive phase storm has no relation and fluctuation is larger. It means that the response of the positive phase storm arrives at all altitudes easier. Especially, the negative phase storm during 22-26 has a smaller change at higher heights when the energy is first coupled into the ionosphere, accounting for about 4% of the lower height, and the height of the maximum absolute change is uncertain. Though the composition is more obvious for the former and the wind field is more apparent for the latter, the combined contribution of atmospheric composition and wind field might be the main causes of the two negative phase storms, and sometimes even the contribution of the ionosphere above 700 km cannot be negligible.
