中文摘要：

在北京城区和城郊利用第二代车载测污激光雷达(AML-2)进行了外场测量实验,利用差分吸收技术从垂直、水平方向分别给出了低层大气中污染物NO2的典型测量数据。结果表明:城区的NO2浓度明显高于城郊地区的水平,并且也证实了利用该系统可以有效地监测低层大气的污染情况,为空气中有害气体的光学遥测提供了有效的测量手段。

英文摘要：

A mobile lidar system used for detecting the content of nitrogen dioxide in lower atmosphere are performed in the field test over Beijing city, and the experiment data are given. The results indicate that the content of nitrogen dioxide in Beijing urban is much higher than that in its suburb. The system can be used to detect the air pollution effectively, and afford a convenient means for optic remote sensing of deleterious gases.
