Title: Preliminary results on the determination of ozone concentration in the atmosphere using the DIAL system

Abstract: Differential absorption lidar (Light Detection and Ranging) technique (DIAL) offers ways to perform measurements for the retrieval of ozone vertical profiles (concentration ppbv) up to 12 km during the nighttime and up to 8 km during the daytime. The system used for this type of retrievals is a DIAL lidar based on a Nd:YAG laser source and Raman shifting techniques to generate several wavelengths in the ultraviolet for the differential absorption technique. This paper presents the methods used in the ozone retrievals and the first profiles over the city of Bucharest.

Key words: DIAL, Raman Shifting, ozone, Differential absorption
