利用海南电离层数字测N~(DPS-4)垂测数据详细分析了由实测数据所得的F2层底部厚度参数最佳值和电离层经验(NeQuiCk)模式计算值之间的差异，最佳值季中值和相对值季中值的日变化、季节变化和年际变化特征。结果表明:(1)在所有季节电离层底部厚度参数最佳值和模式值之间都有不同程度的差异；(2)模式值一般都低估了F2层底部厚度；(3)太阳活动中年，不同年份厚度参数相对值R变化规律一样，相对差异较小。在此研究基础上，对NeQuick的计算模型进行了修正。修正后的模型能够较好地给出海南地区电离层F2层底部电子密度剖面。 |

Using the ionospheric data measured with DPS-4 digisonde at Hainan station,we study the diurnal and seasonal variations of &003B2,the seasonal median values of B2best,and parameter R(ratio of B2best to B2NeQuick2)in the ionosphere.The results show that there are some differences between B2best and B2NeQuick2 in all seasons and B2NeQuick2 is generally less than the values of B2bot at Hainan station.Meanwhile there is the same diurnal variation for R in different years during moderate solar activity and the annual variation of R is very small.Then,we make a revision for formula of NeQuick and results of revised formula show that the B2bot of NeQuick is better consistent with the observations. |
