LIDAR SHOWROOM ............................ What are you going to do with your Lidar today ? Throughout this page you shall discover an innovative range of applications allowed by the easiness, robustness and performances of EZ Lidars. Go ahead and try it ! 1 - Ground field campaigns "Lisair", Paris, May 2005, 30 days The monitoring of the particle mass concentration over polluted areas is currently a serious matter for most urban decision makers. Horizontal mapping of pollution spots can help the authorities improve the efficiency of their policy. LIDAR, for instance, can follow the evolution of aerosol layers, optical depth and mass concentration from one point to another.  From Palaiseau (semi rural) to the center of the Paris's city. The ALS300 has been a recently used during the "LISAIR" air quality campaign in Paris where a mobile LIDAR brought new information on the height dependent behaviour of aerosols and their flow within street canyons. Lastly, as particles can be used as tracers of atmospheric motion, the LIDAR can be used to detect convective cell processes, gravity waves, and other dynamic effects in the atmosphere. On the left picture: - Rise of the concentration near the ground - Uplift of the PBL in Paris downtown   Evolution of aerosol layers and global optical depth from night to morning. Below one can see the residual boundary layer and the birth of PBL in the beginning of the day, the mass concentration is very high in the morning. May 25th 2006 over Palaiseau, France. EZ Lidars, can monitor in 3D the dispersion of pollutants from local sources (plants, roads) towards dwellings.  Daytime horizontal scanning to detect pollution sources over Malakoff, suburbs of Paris. |
