中文摘要：

利用TIMED卫星遥感探测的全球温度分布与NRLMSISE-00大气经验模式进行了对比研究．研究表明，在中间层下部以下的高度范围内，经验模式与卫星探测的大气温度分布有很好的一致性．但是比较发现，在中层顶区域，经验模式的计算结果与实测结果有较大的差异．卫星探测表明，在春分季节的低纬地区中层顶区存在稳定的逆温层，但是经验模式不能给出低纬地区春分季节中间层逆温层的分布特征．卫星观测表明在全球范围内中层顶有两个非常不同的高度，一个处于100km附近，另一个处于85km附近，但是经验模式不能给出这一中层顶高度的分布特征．同时在低热层，经验模式计算的温度分布与卫星遥感的探测结果有很大的差异．

英文摘要：

In this paper, the comparison between the TIMED observed global temperature distribution and the temperature calculated by the NRLMSISE-00 empirical atmospheric model is made. The comparison indicates that in the altitude region between 20-70km, the global temperature structure calculated by the NRLMSISE-00 empirical atmospheric model is consistent with the satellite observation. However, the comparison shows that in the mesopause region, there is obvious difference between the NRLMSISE-00 empirical atmospheric model and the satellite observation. In the vernal equinox season, there is a stable Mesospheric temperature Inversion Layer （MIL） in the lower latitude （20°S-20°N） mesopause region in the satellite observed global temperature data. But the NRLMSISE-00 empirical atmospheric model can＇t produce this feature. The satellite observation indicates that there are two distinctive levels worldwide of the mesopause altitude. One is at about 100 km, another is at about 85 km. This characteristic can＇t be exhibited by the NRLMSISE- 00 empirical atmospheric model. On the other hand, there is large difference of the temperature distribution between the empirical atmospheric model and the satellite observation in the lower thermosphere.
