Dynamic state of the atmosphere in aerosol components

Abstract

An approach to analyzing experimental data on the size distribution and concentrations of atmo spheric aerosol particles and meteorological parameters by using the flicker noise spectroscopy is proposed. This approach makes it possible to identify the character of evolution of the measured parameters due to the processes underlying their variation, to trace the relationship between measured quantities, and, based on this, to determine the mechanisms of interactions between aerosol particles and gaseous components of the atmosphere. As an example, the behavior of the concentration, average particle size, and relative humidity of the atmosphere is examined. Atmospheric measurements were carried out at the recreation center in Tishk ovo (Moscow Region). The proposed approach may prove useful in solving ecological and environmental problems.

Features of the number-size distribution of atmospheric aerosol particles by measurement data on the South-Eastern coast of Lake Baikal (st. Boyarsky) in 2021

“…The particle concentrations at both the inlet and outlet of the diffusion battery are measured to determine the penetration through a set of grids [27]. The inversion algorithm of the DAS data to particle size distribution was developed by Lushnlkov and Zagaynov (1990); Julanov et al, Lushnlkov and Zagaynov (2002), Zagaynov (2012) and Ankilov et al (2002) [28][29][30]. The instrument was running with different particle diameter cut-offs between 5<Dp<1000 nm and individual scan time resolution between 1 and 3 min with the limits of the permissible relative error ±15%.…”
