Abstract

In this paper one demonstrates, based on the measurements achieved, that aerosol optical and microphysical properties and the dominating aerosol type depend on the seasonal climate. In situ measurements of aerosol optical properties were accomplish during an episode starting March to December 2011 at the “Politehnica” University of Timisoara sun photometry station (45.74N; 21.22E), located in the western part of Romania. During different periods such as spring, summer and autumn, the aerosol optical depth (AOD), single scattering albedo (ω), Angstrom coefficients: Angstrom parameter (α) and Angstrom turbidity (β) of urban – industrial aerosols were depicted and the characteristic results were interpreted..

Keywords
