Abstract
The air pollution has been regional in China with the development of economy. To monitoring the air pollution transmission, a new technique, mobile lidar system (GBQ-S01), was introduced. In this paper, a pollution transmission process happened on October 26th, 2017, was analyzed with the use of mobile lidar, air quality monitoring stations data, and Hysplit backward trajectories. The results showed that the polluted air mass was transferred from northeast under the force of air pressure. Under the influences of air pollution transmission and bad meteorological diffusion conditions, The PM10 quality concentrations in Hefei increased a lot within 5 hours; among all the 10 national air quality monitoring stations, the Luyang District (the northernmost one) and Changjiang Middle Road (the easternmost one) received the most serious impact with PM10 concentration reached up to 252 μg/m3 and 219 μg/m3 at 22:00 (Beijing Time).
Highlights
The air pollution in China has been extremely serious, with rapid development of economy but less concern of environment[1]
The mobile lidar observation results showed that aerosols in Hefei and its surrounding areas during navigation were mainly concentrated within 1.5 km altitude
The air pollution could transfer from the north-eastern direction under the force of air pressure
Summary
The air pollution in China has been extremely serious, with rapid development of economy but less concern of environment[1]. With further demand of environment monitoring, mobile lidar was manufactured by integrating the lidar into a motor vehicle. 2. METHODOLOGY 2.1 The mobile lidar system The mobile lidar system (GBQ-S01, Fig. 1), designed and manufactured by Hefei GBo-Qua Technology Co., LTD., having the utility of threedimensional observations of the atmospheric environment, was used in this project. METHODOLOGY 2.1 The mobile lidar system The mobile lidar system (GBQ-S01, Fig. 1), designed and manufactured by Hefei GBo-Qua Technology Co., LTD., having the utility of threedimensional observations of the atmospheric environment, was used in this project This system integrates the aerosol lidar on a vehicle platform with a special data analysis software to present the real-time distribution of particle pollution, from near ground to over ten kilometers, along the navigation path.
