Abstract
Recently, the Romanian lidar group implemented a routine monitoring scheme over Bucharest for the observation of aerosol optical properties in the troposphere. The measurements are provided twice per week at specific times (at 9:00 UT and 13:00 UT) for at least 2 hours per observation time. The purpose is to establish a quantitative comprehensive database of both horizontal and vertical distribution of aerosol over Bucharest and surrounding industrial areas, using a Nd:YAG laser based lidar system, operating at 1064 and 532 nm wavelengths, which provides in real time aerosol profiles up to 10 Km high, with a 6 m spatial resolution. In this paper, a statistical analysis obtained from several months of regular measurements is presented, ordinary and special events being outlined. For further analysis, the integration in atmospheric transport models of aerosol's spatial and temporal distribution derived from lidar measurements and complementary meteorological data was pursued. The novelty of this technique consists in using the OpenGIS technology (Open Geographical Information Systems), which permits the visualization and complex analysis of pollution in natural environment: numerical model of terrain, vegetation, meteorological and atmospheric characteristics. Lidar data are integrated as location type, direction and sense, as from the view-point of their temporal distribution. The position information is processed through an azimuthal projection GIS data server, considering the radial distribution of data centered to the coordinate point of installation location. Several codes were modified in order to obtain forecast aerosols trajectories and to evidence the impact on nearby regions.
