Abstract
A series of polarization spectronephelometer measurements of the angular aerosol scattering coefficients under conditions of extremely dense smoke haze from Siberian forest fires was performed in Tomsk in July–August, 2012. The dispersed composition of the haze comprised ultrafine (particle radii <150 nm) and medium (with the volume distribution peaking around 350 nm) particle fractions. The effective radius of particles was about 220 nm. The smoke haze was characterized by weak absorption; the imaginary part of the refractive index of ultrafine and medium particles had values of ∼0.038 and ∼0.012, respectively. The mean value of the single scattering albedo at a wavelength of 525 nm was about 0.91. In the dense smoke haze, there was a high correlation between volume backscattering and extinction coefficients, an argument in favor of the applicability of a one-parameter model for describing the optical-microphysical properties of the smoke-polluted atmosphere. When smoke haze “decays” (in peripheral zones of smoke plumes), the optical contribution of the ultrafine fraction increases, manifested in an increase in the imaginary part of the refractive index of ultrafine particles up to ∼0.5 and in reducing the albedo from 0.91 to 0.84.
