Research on monitoring illegal air pollution using Scanning Lidar System

The Scanning Lidar System (SMART MK-II) analyzes light backscattered by particles in the air and calculates information about fine dust mass concentration with distance. fine dust concentration in real time and continuously was observed with a resolution of 30 m within a radius of 5 km using the Scanning Lidar System, and used to analyze air quality around industrial complexes. The observation location was the rooftop of the Tech University of Korea second campus building located in Siheung, Korea (37.32792, 126.6892). The optimal measurement site for the Scanning Lidar System was selected and the surrounding air pollution was observed horizontally by adjusting the height. This is a study to build advanced monitoring system that tracks illegal emission sources, focusing on areas(heat-map) with high concentrations of fine dust. Instead of randomly cracking down on illegally businesses and factories emissions source, the crackdown system was changed to focus on areas with high air quality concentration and high emissions by the advanced air monitoring system. The final goal of this study is to use the Scanning Lidar System visualization program to provide location notification services for areas with high fine dust concentration and suspicious air emission sources. It was used to crack down on illegal air emissions projects and inspect air pollution prevention facilities, and had the effect of reducing health damage caused by fine dust and improving air quality.
