摘要：

Long duration observational run by the EISCAT Svalbard Radar (ESR) and ionosonde in Zhongshan station which are at conjugated location during International Polar Year (IPY) in solar minimum, have been analyzed with respect to variability in the F2-layer peak parameters. The comparison between the International Reference Ionosphere (IRI-2007) and the observation data clearly demonstrates the conformity in summer, but greater deviation in winter. It suggested that though the IRI model considered the F2 peak parameters dominated by the solar photoionization well, the electron precipitation effects should be taken into account as well, especially in winter.

It suggested that though the IRI model considered the F2 peak parameters dominated by the solar photoionization well, the electron precipitation effects should be taken into account as well, especially in winter.
