【摘要】：本文采用散点图、趋势线、相关系数及观测偏差等统计方法,利用COSMIC卫星和SPIDR提供的垂测仪观测的F_2层峰值电子密度数据,开展了综合统计及按季节、地方时和纬度的分类统计.统计结果显示:地基垂测仪与卫星观测到的相应的F_2层峰值电子密度数据具有很高的相关性,两者之间的相关系数高达0.95,相对偏差的平均值为-3.38%,标准差为19.54%.基于上述研究结果,提出了利用地面垂测仪观测数据验证卫星观测的电离层结构参数的方法,并给出了定性的判别依据和定量的判别标准,可在我国电磁监测试验卫星发射后,为F_2层峰值电子密度观测数据的真实性和有效性提供检验方法和保障.
[Abstract]:In this paper, the statistical methods such as scattered plot, trend line, correlation coefficient and observation deviation are used to develop comprehensive statistics and seasonality based on the FSP 2 peak electron density data observed by COSMIC satellite and SPIDR. Classified statistics of local times and latitudes. The statistical results show that there is a high correlation between the ground-based vertical measurement instrument and the satellite observations of the corresponding two-layer peak electron density data. The correlation coefficient between them is as high as 0.95, the average relative deviation is -3.38 and the standard deviation is 19.54. Based on the above research results, a method for verifying the ionospheric structure parameters of satellite observations using ground vertical observation data is put forward, and the qualitative and quantitative discriminating criteria are given, which can be used after the launch of the electromagnetic monitoring test satellite in China. It provides the verification method and guarantee for the authenticity and validity of the F-2 layer peak electron density observation data.
