At the Lidar Division of CEILAP laboratory, the development of a multiangle Raman lidar is reaching its final stage. As emission system, a Inlite II-50 from Continuum is used. It is a Nd:YAG laser with 125 mJ @ 1064 nm and a divergence assured to be less than 0.7 mrad. The reception system is made by six newtonian telescopes of 40 cm diameter and 1 m focal length each, producing a total collection area close to 1 m2. The electronic acquisition is performed by a Licel transient recorder model TR 40-12. The aim of this lidar is to obtain aerosols attenuation over certain zenithal/acimuthal angles with elastics and Raman lidar signals. A new robust scanning system was deployed inside a shelter-dome, and the electronic/software to bring the scanning capabilities is close to be finished. First signals are already taken to probe laser-telescope stability. In this work, first multiangle lidar profiles and a preliminary data analysis is reported.
