Abstract
The aim of this project is the measurement of urban pollution in the Magurele platform (near Bucharest city where the pollutant sources are known) using LIDAR system operating at 532 and 1064 nm wavelengths. The application is based on the remote detection of aerosols in the atmosphere using a Smoke Analyzer by sending a short light pulse and receiving the radiation scattered in backward direction that provides backscattering signal as a function of distance. The observable backscattered signal is generated by air density fluctuations (Rayleigh scattering) and by small aerosol particles always present in the atmosphere. The presence of aerosol particles gives rise to an increase of the backscattered signal and thus the aerosol flow can be detected on the background surrounding clean atmosphere. In these applications, it is important the response time to be as shorter as possible, and the sensitivity to be very high, in correlation with an eventual alert when the pollutants exceeds a risk threshold. Therefore processing the lidar data constitutes an important factor in obtaining air quality information. This papers presents first results obtained in Romania by direct lidar measurements in the area of Bucharest and the original software developed by the Environmental group in INOE for lidar data processing and PBL height identification.
