LIDAR (Light Detection And Ranging)is a remote sensing technology that can distinguish DSS particles which cannot be seen with the naked eye from other atmospheric pollutant particles (e.g. air pollutants), and that can monitor such particles on a real-time basis. In this page, the concentration of DSS near the ground is estimated and represented as cylinders based on the monitoring results (provisional data) of LIDAR.
