为了满足在区域尺度上大气气溶胶垂直分布的探测需求,在中国科学院重大科技基础设施项目“航空遥感系统”的资 助下,研制了机载双波长偏振激光雷达。介绍了该机载激光雷达的主要功能和性能参数,以及在华北地区开 展的飞行观测实验,取得的结果表明,该机载激光雷达性能稳定,其探测精度达到设计要求,可以为污染源的识别和 传输路径的探测提供高时空分辨率的数据,为认知大气气溶胶的微物理特性和分类提供了重要的机载遥感平台。

Sponsored by the project named “National Aeronautic Remote Sensing System”, an airborne two-wavelength polarization lidar is designed for detecting three-dimensional distributions of atmospheric aerosols. The field campaign, as well as the structures and key parameters of the lidar system are described. The preliminary result shows that this airborne lidar is well constructed and robust which can provide a significant airborne remote sensing platform for monitoring the aerosol’s optical and physical properties.
