介绍了一种新型边界层气溶胶监测激光雷达的总体结构及各部分的功能,分析讨论了该激光雷达的几何重叠系数测量结果及北京丰台地区的外场实验结果,探讨了大气边界层内气溶胶消光系数与湿度、风速等气象条件的关系,实验结果表明:水平大气气溶胶消光系数与BC质量浓度、地面风速等近地气象因子均有较好的相关性,该雷达性能优越,结果可靠。
A new type of boundary layer aerosol monitoring laser radar’s overall structure and functions of each part are introduced. The geometrical overlap coefficient measurement results of the laser radar and the field experiment results in Beijing’s Fengtai area are analyzed. The effects of aerosol Extinction coefficient and humidity, wind speed and other weather conditions. The experimental results show that the horizontal atmospheric aerosol extinction coefficient has a good correlation with near-surface meteorological factors such as BC mass concentration and surface wind speed. The radar has superior performance and reliable results.
