Comparative Analysis of Laser Radar for Tracing Atmospheric Particulate Matter

本文利用激光雷达的水平、垂直扫描方式，分别对砚山工业园区进行一个月的颗粒物溯源监测，根据不同扫描方式的监测数据，探讨了两种扫描方式在监测范围、空间范围、数据和时间连续性、溯源效果等方面的差异。研究发现，水平扫描在近地面污染物分布监测方面具有优势，而垂直扫描则更适用于大气垂直结构研究。基于两种扫描方式的特点，提出了融合应用方案，为提高大气环境监测的全面性和准确性提供了新的思路。This article uses the horizontal and vertical scanning methods of LiDAR to conduct a one month particle traceability monitoring of Yanshan Industrial Park. Based on the monitoring data of different scanning methods, the differences between the two scanning methods in monitoring range, spatial range, data and time continuity, traceability effect, etc. are explored. Research has found that horizontal scanning has advantages in monitoring the distribution of pollutants near the ground, while vertical scanning is more suitable for studying the vertical structure of the atmosphere. Based on the characteristics of two scanning methods, a fusion application scheme is proposed, providing new ideas for improving the comprehensiveness and accuracy of atmospheric environment monitoring.
