biomass burning aerosols, remote sensing, LIDAR;

At the end of April 2015, a large vegetation fire occurred around the Chernobyl nuclear plant, leading to emission of radionuclides in the atmosphere. The influences of biomass burning aerosols from this intrusion event over urban/industrial load were evidenced in this work by monitoring and analysis of optical properties of tropospheric aerosols from two RADO (Romanian Atmospheric 3D Observatory) monitoring sites: INOE_Magurele, near Bucharest and Iasi_LOASL. In order to obtain information concerning the aerosol layers, dynamics and their optical properties, two LIDAR systems were used: a Multiwavelength Depolarization Raman lidar at Bucharest and an elastic backscatter lidar at Iasi. The data provided by the AERONET sun-photometers network were used to identify the biomass burning aerosols influences nearby the lidar measurements sites. HYSPLIT back-trajectories and FLEXPART dispersion model were also used in order to estimate the source and evolution of the long-range transported aerosols.
