Title: Lidar monitoring of aerosols loading over Bucharest

Abstract: Recent estimations showed that the possible impact of aerosols (both direct and indirect effects) on the radiative forcing (cooling effect) in a global average is of the same order of magnitude as the CO2 effect (warming effect). For this reason, long-term observations of aerosols vertical profiles and their temporal evolution are to be done, mainly in highly polluted areas, in order to evidence their influence on climate. The aim of our work is to study urban pollution in connection with meteorological data over Magurele research platform, in the proximity of Bucharest city, using a LIDAR system operating at 532 and 1064 nm wavelengths. The application is based on the remote detection of aerosols by sending a short laser pulse in the atmosphere and analyzing the backscattered radiation. First results obtained by the scientists in the Environmental group of INOE (Institute of Optoelectronics, Bucharest) using an elastic backscatter LIDAR for industrial and traffic originated aerosols are presented in the paper.
