Abstract:

Variability is considered of medium size fraction of ground aerosol particles with radii of 0.3–0.6 μm during the winter–spring change in the experiments carried out at aerosol station LOA IAO SB RAS in 2009–2013. The time variations of aerosol extinction coefficient for the spectral range 0.50–3.9 μm obtained along a surface path and a function of particle size distribution in the range 0.2–5.0 μm measured using a photoelectric counter PKGTA at one end of the path are analyzed. Connection of the variations of medium size particle concentrations and submicron aerosol condensation activity are studied. The experimental spectral attenuation coefficients are compared with calculated by the Mie theory for the approximate size distributions.

Keywords:

medium size aerosol, spectral aerosol scattering, condensation activity
