中文摘要：

利用大气分子的纯转动信号反演大气温度，被证明是一种精度很高的方法，目前已得到广泛的应用并在世界各地建立起多台纯转动拉曼激光雷达．全部的纯转动拉曼谱线之和是不依赖于温度的，利用这个特性，可以不需要任何的假设，反演大气气溶胶的消光．本文介绍了一种新的探测大气气溶胶的方法，首次提出通过提取纯转动单支谱（-4和14），加上Rayleigh＆Mie通道的激光雷达方程，不需要附加任何假设，导出了气溶胶后向散射系数的数学表达式．

英文摘要：

It has been proved to be a high precision method to use pure rotational Raman signal of atmospheric molecules to inverse atmospheric temperature and many stations of pure rotational Raman lidar have been established around the world. The addition of all pure rotation Raman spectra is independent of the temperature. Using this feature we can invert aerosol extinction without any assumptions. This paper presents a new method of aerosol detection, extraction of pure rotational spectrum of a single branch （J=4 and 14）, coupled with Rayleigh ~ Mie channel lidar equation, without any requirement of the additional assumptions. We derive the mathematical expression of the aerosol backscatter coefficient.
