大气温度和湿度廓线的CT遥感方法仿真研究

本文讨论了ＣＴ（计算机层析扫描）技术在廓线反演中的应用，７个适合本研究特点的红外光谱通道被确定，对温度和湿度廓线截面作了数值仿真，并与常规的正对地观测反演作了比较，结果表明ＣＴ方法可以提高温度反演精度达２０％以上，而湿度的反演则表现出对先验信息的较强依赖性．

Research on Atmospheric Temperature and Moisture Profiles Retrieve by Computed Tomography Method

This paper investigates in several new aspects the CT(Computed TOmography) technology applied to the inversion of atmospheric temperature and moisture profiles. Seven independent channels of IR sensors are selected and analyzed by Eigen-value analysis.With these channels, the CT retrieval process is simulated numerically and compared with the results by the conventional reverse method. The results show that for temperature profiles retrieve CT technology is better 20 % in precision than the conventional way.For moisture profiles, the retrieved results depend on the priori knowledge of profiles and the equation system shows poor stability while changing the primary profiles.
