从1987年至今，国防气象卫星方案（DMSP）的航天器提供了在四个当地时间区段中所有纬度840公里高度上的总离子密度的测量结果。因此，过去太阳活动周期的所有阶段都反映在数据集中。我们目前的测量值从电离层的气候学模型得到的比较。研究的模型是国际参考电离层（IRI）模型，参数化电离层模型（PIM）和Reilley-ICED-Bent-Gallagher（RIBG）模型。我们发现，所有的模型再现了一些观测到的顶侧电离层的功能，但没有一个模型匹配所有的观测。
Measurements of total ion density at 840 km altitude at all latitudes in four local time sectors are available from 1987 to the present from spacecraft of the Defense Meteorological Satellite Program (DMSP). Thus all phases of the past solar cycle are represented in the data set. We present comparisons of the measurements with values obtained from climatology models of the ionosphere. The models examined are the International Reference Ionosphere (IRI) model, the Parameterized Ionospheric Model (PIM) and the Reilley‐ICED‐Bent‐ Gallagher (RIBG) model. We show that all of the models reproduce some of the features of the observed topside ionosphere, but none of the models match all of the observations.
