LIDAR (Light Detection and Ranging) is the only remote sensing technique that is capable to provide 3-dimensional range resolved measurements of atmospheric constituents like pollutants, humidity or the aerosol, and of atmospheric parameters like temperature or wind. Further perspectives arise from the advent of ultra-fast high-power laser sources which are capable to generate extended plasma channels in the air, so called filaments. Their extraordinary properties, like backwards-enhanced white light emission, plasma generation along their trajectories, and their electrical conductivity provide further fascinating perspectives for applications in atmospheric research and beyond. Examples are remote multi-component analyses of the air and the aerosol, bio-aerosol detection, hard target analysis and even lightning control.
