DEVELOPMENT OF A LASER REMOTE-SENSING SYSTEM (LIDAR) FOR AEROSOL AND OZONE VERTICAL PROFILE MEASUREMENTS IN THE LOWER TROPOSPHERE

In this paper is presented the development of a multiwavelength LIDAR system (the first in Greece) for daytime and nighttime vertical profil e measurements of ozone and aerosols in the lower troposphere (0.5-4 k m). This LIDAR system uses state-of-the-art solid-state laser and elec tronic technologies and is designed to be rugged, modular and simple t o operate. The LIDAR wavelengths used are the 266 nm, 289 nm, 299 nm, 355 nm, and 532 nm, all derived from a pulsed Nd:YAG laser. Further, i n this paper, we present the scientific objectives of the LIDAR Projec t and briefly describe the technical characteristics of the system dur ing the various integration phases and report on the expected measurem ent accuracy.
