A direct inversion method for transform function curve in vertical electric sounding

The data of 5 ionospheric vertical sounding stations before 4 earthquakes in Japan are analyzed. It is found that most of the critical frequencies of the E sporadic layer tended to decrease and the only few tended to increase around the epicenters before and after the earthquakes.

分析日本4次地震前5个电离层垂测站资料，发现地震前后震中附近夜间电离层偶发E层的临界频率f0ES值多数呈下降趋势，少数呈增加趋势。

The meteorological satellite sounding data has been used in numerical forecast in many countries. This paper introduces the methods for retrieving atmospheric temperature profiles from meteorological satellite vertical sounding data and the calculations of regression retrieval coefficients used in the statistical method.
