Abstract
The paper shows the results of aerosol quasi-synchronous study. We have researched chemical, mineral, and disperse composition of the insoluble fraction of aerosols in snow as well as PM2.5. In winter period 2012/13 samples were collected in the background and urban sites where IAO SB RAS stations are located. There is a good correlation between obtained and synoptic data. It makes it possible to detect some sources of aerosols. Studies revealed the mineral modes of some chemical elements in the insoluble fraction of aerosols in snow and PM2.5.
