基于激光雷达技术的太原典型雾霾天气研究
|
摘要
由于太原独特的气候和地理位置,每年冬季供暖期间雾霾天气反复出现,严重影响人们的健康和正常生活。采用EVE低功率激光器对太原市雾霾天气进行监测,通过消光系数、退偏比和PBL等参数系统分析研究污染天气的特征,结果表明:西南、西北方向的污染迁移传输是太原市空气质量恶化的主要原因,空气质量的提高依赖于较大持续风力的出现和对相邻区域的污染监测、管理。
Because of the unique climate and geographical location in Taiyuan,fog and haze weather occur repeatedly in winter,which has seriously affected the health and normal life of people. In order to improve the air quality in Taiyuan,the EVE low power laser is used to monitor haze weather,and the characteristics of haze weather are systematically analyzed through extinction coefficient,depolarization ratio and PBL parameters. The result shows that the pollution that transfer and transport in the southwest and northwest are the main reasons of the deterioration of air quality in Taiyuan. The improvement of air quality depends on the appearance of larger sustained wind power,and effective pollution monitoring management for adjacent areas.
