应用CALIPSO(Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation)卫星数据,对大气中的气溶胶等目标进行了去偏振度计算及分析。结果表明,目标后向散射去偏振度信息,能够很好表征大气气溶胶的构成种类、目标特征、垂直高度分布等特性。气溶胶的去偏振特性,为大气气溶胶的特性与分布情况等研究提供了新的方法与定量化参考参数。CALIPSO数据研究方法和结果,对全球气候变化原因、大气污染、沙尘暴等研究有重要的参考价值。

The depolarization ratio of the targets in the atmosphere was caculated from the CALIPSO satellite data.From the results it can be seen that the depolarization ratio can characterize the category,the characteristic and the verticle altitude of the aerosol in the atmosphere.The depolarization ratio of the aerosol applies the new method and believable parameter for the research of the aerosol.And the CALIPSO satllite data analyse result of this paper also gives new insight into the research about the reason of the global climate change,the pollution of the atmosphere,Saharan dust and other types of aerosol.
