| 摘 要： | 在对流层(小于12km），由于大气中气溶胶的存在，传统的利用大气中瑞利散射光谱测量大气温度的方法具有一定的局限性。借助傅里叶分析方法对不同高度的大气后向散射光谱通过碘吸收池所产生的不同透过率曲线进行处理，同时考虑了对流层中气溶胶的影响，可得到对流层中不同高度、不同大气后向散射比条件下的温度轮廓线。

| Abstract: | Owing to the presence of aerosol in the troposphere(below 12km), traditional method which uses Rayleigh scattering spectrum to measure the atmosphere temperature has certain limitations. This paper uses a Fourier analysis method to proceed transmission curve produced by atmospheric back-scattering spectrum through the iodine cell, considering the influence of the aerosol. This method can obtain the temperature profile of the troposphere under the condition of different height and different back-scattering ratio. |
