摘要

摘要: 电离层峰值高度H_mF₂是描述电离层形态的重要参数之一，国际参考电离层模型IRI-2016中融入了大量电离层测高仪和无线电掩星探测数据，用以提升H_mF₂的预测精度.本文利用太阳活动低年（2007—2010年）气象、电离层和气候卫星联合观测系统COSMIC探测数据描述全球范围内COSMIC H_mF₂的三维形态变化，对比分析了IRI-2016与IRI-2012模型的预测结果，同时分析了IRI-2016模型输出H_mF₂的性能.结果表明，IRI模型在中高纬度地区的输出结果高于COSMIC反演结果，而赤道及低纬地区则大都偏低.与IRI-2012模型相比，IRI-2016模型的输出结果在夜间至凌晨时段呈现较为明显的纬向梯度变化且大部分区域输出值偏高，但在白天时段赤道附近区域的输出值大都偏低.上述结果为电离层IRI模型的完善提供了一定参考.

Abstract: Because ionospheric peak height H_mF₂ is one of the important parameters describing the ionospheric morphology, new models based on digisonde station data and radio occultation data was included in the latest version IRI-2016, and the changes and improvements of the H_mF₂ prediction would be expected. In this work, Global three dimension variations of H_mF₂ from the Constellation Observing System for Meteorology, Ionosphere and Climate (COSMIC) are described using the 4- year dataset during the period of 2007-2010. Meanwhile, H_mF₂ predictions by the model IRI-2016 and IRI-2012 are analyzed in order to evaluate the performance of IRI-2016. Comparisons between COSMIC and IRI show that IRI-derived H_mF₂ values are high in the middle and high latitude regions and whereas they are relatively low in the equator and low latitude regions. During the period of midnight, H_mF₂ by IRI-2016 is characteristic of latitudinal gradient, and notably is higher than that by IRI-2012 in the part of the mid-high and the low-latitude regions. However, H_mF₂ from model IRI-2016 in most equator regions and low-latitudes is lower than IRI-2012 in the daytime. Analysis of ionospheric H_mF₂ provides valuable references for the future improvement of ionosphere model.
