The scale height in the plasmasphere ($H_P$) is an important factor to present the dynamic nature and variations of the plasmasphere. It is challenging to build reliable plasmaspheric scale height model because of poor coverage and limited continuity of plasmaspheric sounder data. In this paper, an empirical orthogonal function (EOF) analysis method is applied to organize the $H_P$ obtained from total electron content (TEC) measurements of precise orbit determination (POD) antennas and electron density profiles of Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC) mission, from the year 2007–2014, to reconstruct a global plasmaspheric scale height model. The model depends on parameters including the month of the year, the local time, the geographic latitude and the solar radio flux index F10.7. Comparison of this model and the scale height deduced from the International Satellites for Ionospheric Studies (ISIS) data shows remarkable consistency in $H_P$ values and variations.

等离子层中的标尺高度（$H_P$）是呈现等离子层动态性质和变化的重要因素。由于等离子层探测仪数据的覆盖范围较差且连续性有限，因此建立可靠的等离子层标高模型具有挑战性。本文采用经验正交函数（EOF）分析方法来组织$H_P$从2007-2014年从精确轨道确定（POD）天线的总电子含量（TEC）测量结果和气象，电离层和气候星座观测系统（COSMIC）任务的电子密度分布图获得），以重建全球等离子层规模高度模型。该模型取决于参数，包括一年中的月份，当地时间，地理纬度和太阳辐射通量指数F10.7。该模型与国际电离层研究卫星（ISIS）数据推导出的标尺高度的比较表明，$H_P$ 值和变化。
