Paper Abstract

Regular round-the-clock measurements of the total number density and disperse composition of aerosol particles of the radius range r=0.2-0.5 μm carried out at the aerosol monitoring station of LAO IAO SB RAS since 1999 till 2004 by means of the photoelectric counter of particles PKGTA make it possible to study temporal characteristics of the measured parameters in a big data array. In this message diurnal behavior of the absolute values of the the total number density N (r=0,2-5 μm), number densities of each fraction Nsub(r(=0,2÷0,5 μm) and Ncoarse(r=0,5÷1 μm), the values of these parameters normalized to the diurnal mean values and the integral parameter Kf=Nsub/Ncoarse is analyzed. Diurnal behavior in different seasons (winter, spring, summer and autumn) is considered. Diurnal behavior of the aforementioned parameters was studied under conditions, when the cloud fraction varied with the limits 0 ÷2, F=(4π/3)ri3ΔNi/Δri is analyzed. The peculiarities of the diurnal behavior of the aforementioned parameters and possible reasons affecting the diurnal behavior are discussed.
