Abstract We have used a ruby Lidar to study the space and time variations of atmospheric aerosols on a horizontal level above a town site. It has allowed us to locate the main sources of industrial pollution and to evaluate the amplitude of retrodiffusion signals due to the town activity. We have demonstrated the influence of the winds whose speed is higher than 3 m/s. We have observed that at any particular place in the town the ratio Am/Amo varied from 1 to 14, this radio characterizing the concentration in pollutants above a place in the town (Am is the amplitude of the retrodiffusion Lidar signal, Amo is the echo lidar amplitude characterizing the average noise of the urban site).
