中文摘要:
      介绍了激光雷达通过垂直扫描、水平扫描和车载走航等方法在湖北大气环境监测中的应用实例。利用地基激光雷达并结合星载激光雷达监测一次沙尘传输过程,沙尘传输高度为500~4 000 m之间,且出现3次尘降,地面PM10出现3次峰值。利用激光雷达探测大气边界层高度,颗粒物浓度受边界层高度影响,当边界层高度降到500 m以下时,PM2.5浓度达到120 μg/m3,边界层高度上升到1 500 m以上时,PM2.5浓度降到30 μg/m3以下。利用激光雷达水平扫描技术,对襄阳市高新区污染物的影响进行溯源,监测得出颗粒物浓度上升的主要原因为地面扬尘。利用激光雷达车载走航监测技术,监测黄冈市颗粒物空间分布特征,在不同区域监测到2处污染扩散带,分别位于工业区与生活区。
英文摘要:
      In this study, combining space-borne and ground-based lidar, a dust transmission process in Hubei was investigated by vertical scanning, horizontal scanning, and mobile platform based scanning. Dust particles mostly occured from 500 m to about 4 000 m, and were mainly contributed to high concentration of coarse particulate matter (PM10) in near surface. Moreover, the concentration of particles was distinctly affected by the height of the boundary layer. The concentration of fine particulate matter concentration (PM2.5) reached 120 μg/m3 at the boundary layer height below 500 m, while the concentration of PM2.5 dropped below 30 μg/m3 when the height of the boundary layer rises above 1 500 m. Using lidar horizontal scanning technology, the impact of pollutants in the high-tech zone of Xiangyang was traced. The results showed that the main reason for the increase of PM2.5 concentration was dust on the ground. Furthermore, we found that industrial and living areas were the most of pollution origins in Huanggang based on mobile monitoring technology to monitor the spatial distribution characteristics of particulate matter.
