PKNU invented a LiDAR system that monitors and scans fine dust in real-time It is the ’High-Resolution Scanning LiDAR System for Monitoring the Distribution of Fine Dust’ developed by the research team of Professor Noh Young-Min (Combined Departments of Environmental Engineering) at Pukyong National University.
LiDAR is a remote sensing technology that detects the concentration and distance information of the target material we want to observe through the method of irradiating a laser. The research team of Prof. Noh Young-min of Pukyong National University developed this system in collaboration with Hanbat National University and Samwoo TCS Co., Ltd. with the Grant & Alliance (R&D) Project Team (Jo Dae-Hyeon, Team Leader) under Korea Agency for Infrastructure Technology Advancement (KAIA), Siheung City, and the Advanced Institute of Convergence Technology. The research team installed this system in Siheung, Gyeonggi-do from September last year to perform observations, and successfully demonstrated by visualizing and expressing the high-resolution mass concentration distribution map of fine dust that could not be provided by the existing air pollution measurement network. The Ministry of Environment has excellently evaluated the system’s ability to detect the spatial distribution map of fine dust and decided to operate a test project for monitoring illegal incineration in rural areas by installing the system in Jeonbuk during the 2nd seasonal fine dust management period (Dec.2020~Mar.2021). Accordingly, Prof. Noh’s research team plans to install a scanning LiDAR system in the region at the end of January and conduct observations for two consecutive months from February to March. Prof. Noh said, "In order to overcome the limitations of the method of cracking-down on illegal incineration in rural areas using human resources so far, it is expected that by conducting continuous observations using the scanning LiDAR system, basic data that can remotely detect the current status and emissions of fine dust can be calculated." <Pukyong Today> |
This system introduces a scanning method to LiDAR technology, and it is a system that can calculates the measured value by dividing the mass concentration of fine dust into PM10 (fine dust) and PM2.5 (extra-fine dust) with a high resolution of 30 m in an observation area with a radius of 5 km.
