The monitor of particles in the atmosphere, as well as the study of their dynamics, becomes every day more important and the main technique for remote sensing is the Lidar. Despite its effectiveness, aerosol Lidar can be used only during the night to avoid sunlight background photons and because it is not eye-safe. These limitations can be overcome using a 1550 nm laser but silicon-based single-photon detectors have a very low signal-to-noise ratio at this wavelength. In this work we show the results of a Lidar measurement using a 1550 nm laser and a SNSPD detector.
