Abstract
The annual behavior of concentration of an organic component of the atmospheric aerosol which is selected from a board of the Tu-134 “Optic” airplane-laboratory in the atmospheric layer of 500-8500 m is investigated. It is revealed that the greatest concentration of the organic components as a part of the aerosol is observed in spring, the smallest, in the fall. As a part of aerosol particles compounds from C
8H
18 to C
35H
72 are found. The range is widest during the winter period (C
12H
26-C
35H
72) and in spring (C
8H
18-C
31H
64). In the summer (C
18H
38-C
33H
68) and in the fall (C
16H
34-C
31H
64) it is noticeably narrower. During the whole year as a part of an aerosol one mode (n-alkane C
20H
42) dominates. During the summer period there is a secondary maximum, falling on the n-alkane C
29H
60.
