| 摘 要： | 激光雷达探测大气温度通常采用探测大气分子瑞利散射的方法 ,这种方法由于低层气溶胶的存在 ,一般只能探测高空 (约 12km以上 )的大气温度。本文介绍了利用高光谱分辨率激光雷达探测大气温度的方法 ,可得到大气中不同高度、不同大气后向散射比 (Rb)条件下的温度轮廓线。结果表明此方法可用于大气温度垂直剖面探测

| Abstract: | Rayleigh Scattering method is used to detect atmosphere temperature in lidar.Owing to present the aerosol at the low altitude.This method can only detect the atmosphere temperature at the high alititude(>12 Km).This paper represents a method which uses high spectrum resolution lidar to detect the atmosphere temperature.This method can obtain the temperature contour at the various height and on the condition of various back-scattering ratio.The results show that this method can be used to detect vertical section temperature of the atmosphere. |
