THE EOLE PROJECT - A MULTIWAVELENGTH LASER REMOTE-SENSING (LIDAR) SYSTEM FOR OZONE AND AEROSOL MEASUREMENTS IN THE TROPOSPHERE AND THE LOWER STRATOSPHERE .1. OVERVIEW

A multiwavelength Laser Remote Sensing (LIDAR) system (EOLE Project) f or daytime and night-time vertical profile measurements of ozone and a erosols in the troposphere and the lower stratosphere (0.5-15 km) is p roposed. The EOLE lidar system uses state-of-the-art solid state laser and electronic technologies and is designed to be rugged, modular and simple to operate. Further, in this paper, we present the scientific objectives of the EOLE Project and briefly describe the experimental s et-up of the EOLE lidar system. The expected measurement accuracy, in both ozone and suspended particles (aerosols) observations, is briefly discussed, as well as the calibration procedures of the proposed lida r system.
