Lidar map of air pollution. Map showing the density of airborne particulates over Albuquerque,New Mexico,made using a Lidar system. The colours represent the concentration of particulates in the air,from red (highest concentration) through yellow and pale blue to dark blue (lowest). The worst pollution is over a truck refuelling station next to a motorway junction. The yellow lines are roads. Lidar (Light Detection and Ranging) uses a laser to scan an area of sky. A telescope is coupled to the laser,and measures the amount of light scattered by air pollution back to the instrument | |
