Inner-seasonal factors of variability of submicrometer aerosol optical characteristics

The data analyzed on the direct scattering coefficient of the aerosol 'dry matter' (mu) (45 degrees), parameters of condensation activity of aerosol particles (gamma) , and thermo- optical parameters F equals (mu) (25 degrees C)/(mu) (100 degrees C) and Q equals (mu) (250 degrees C)/(mu) (100 degrees C). Resulting from the analysis of the power spectrum of the scattering coefficient (mu) (45 degrees), it is revealed that the principal frequencies of this parameter are observed both on the inner-day values (12 and 24 hours) and on the periods of approximately 2, 3, and 8 days. It is more reasonable to relate them with synoptic processes. Thermo- and hygro-optical parameters (gamma) , F, and Q have the more weak variations than (mu) (45 degrees).
