An attempt to apply the wavelet and harmonic analysis to the array of experimental data on the atmospheric aerosol mass concentration and the total protein concentration in surface air in the vicinity of Novosibirsk in 2001-2002 has been undertaken. The wavelet analysis of the data has shown that surface air concentration variations are mainly determined by characteristic synoptic processes with the periods of 4, 7, 10, and 15 days. The results of harmonic analysis have shown that the synoptic variations average from 40 to 70% of the concentration variations and reach 90% in spring.
