Resumen
The lidar for clouds and aerosols (Lidar Nuage Aerosol, LNA) is operated at Palaiseau (25km south of Paris in France) on the ?Site Instrumental de Recherche par Télédetection Atmosphérique? (SIRTA[1]). The instrument is developed to retrieve the optical and microphysical properties of clouds and aerosol in the boundary layer and troposphere between 0.1 and 15 kilometers. The LNA is operating since 2001 to observe routinely backscattered vertical profiles of the atmosphere. Many applications take advantage of lidar-radar synergy to analyze clouds microphysical properties, cloud dynamics and cloud macrophysics. Lidarradiometer synergy are used to retrieve cloud microphysical properties in preparation of the CALIPSO mission. A description of the instrument and its performance is provided and the algorithm developed to retrieve the macrophysical structure of the atmosphere is presented. Key words: Lidar, backscattering, optical properties, microphysical properties, clouds
