Abstract
The paper presents the analyses of different aerosol type over Timisoara, Romania. The study is relying on detailed physical and optical aerosol properties, data collected from the sun photometer located at Mechanical Engineering Faculty, Politehnica University Timisoara during 2011 and 2012. By analysing aerosol optical depth (AOD), Angstrom parameter (alpha), single scattering albedo and size distribution the types of aerosol are determined. A high AOD (>0.6) and a low value of Angstrom parameter (alpha<0.6) represents an atmosphere with dust, respectively if alpha>1.5 the atmosphere is loaded with biomass burning aerosol. Also, for industrial aerosol or urban pollution the aerosol optical depth is between 0.3 and 0.6 and the Angstrom parameter takes values from 1.2 to 1.6. Dust and biomass dispersion was investigated by using NOOA HYSPLIT model (Hybrid Single - Particle Lagrangian Integrated Trajectory). Other main parameter calculated in this study is Angstrom turbidity coefficient which values are from 0 (clear atmosphere) to 0.5 (high aerosol load). Global Fire Maps from MODIS (Moderate Resolution Imaging Spectroradiometer) were used to identify biomass burning sites.
