Variations of aerosol microstructure under the effect of smokes as assessed from the results of inverting the data of spectral optical measurements

摘要

In this paper we discuss the results of the spectral aerosol optical thickness (AOT) of the atmosphere obtained in 1999, 2003 and 2004 during the periods, when significant increase of the atmospheric turbidity was observed under the effect of near Tomsk forest fire smokes and smokes coming with remote transfer of air masses. Measurements of the spectral transparency of the atmosphere were carried out by means of a multi-wavelength sun photometer in the wavelength range 0.37-4 um. The dynamics of the daily mean values AOT is considered at presence of smoke in the atmosphere during several days, as well corresponding transformation of the aerosol microstructure obtained from solution of the inverse problem.
