Abstract

This paper presents Raman-Lidar experimental results in minor species detection.

That mainly concerns two kinds of measurements:

- detection of ozone in the atmosphere, using resonance Raman Scattering and of CO₂ using Raman scattering;

- identification and measurement of pollutant gases (SF₆, SO₂, and CO₂) in a simulation tank.

From these preliminary results, the detection limits of the system are estimated and simulations of pollutant plume measurements are performed taking spectroscopic problems into account.
