Paper Abstract

Ambient air pollution with particulate matter constitutes a significant public health danger. The potential health effect depends on parameters of suspended particles. The paper develops a procedure for studying aerosol microstructure variability in the lower atmospheric layer over the territory of an industrial center by a multi-wavelength scanning lidar and a Sun-sky radiometer. An algorithm for data processing of a comprehensive experiment uses integral optical parameters of the aerosol layer provided by the radiometer as a prior information to process lidar data while retrieving spatial distribution of aerosol microstructure. A long series of combined lidar and radiometer measurements have been carried out in Minsk. The observed temporal changes of total column amount of fine and coarse aerosol fractions are discussed in the paper. Statistical characteristics of particle size distributions have been evaluated. The spatial variability of fine and coarse aerosol fraction concentrations was observed over the city. Comparison of aerosol concentration distributions during two year observations reveals stable zones with increased concentration of fine particles, possible reason being technological peculiarities of industrial enterprises located in these regions.
