Project summaryThe investigation of spatial and temporal variability of gas and aerosol contamination in the atmosphere of background regions of the Baikal lake and background station Mondo is the main goal of this project proposal. Since there are a number of anthropogenic pollution sources located in industry plants in the Baikal region, it is very critical to compare the chemical composition of atmospheric gases and aerosols for the Baikal and Mondo regions during different seasons as well as estimate pollutants transport in the atmosphere. As the aerosol particles may be regarded as a terminal phase of the existence of gaseous species in the atmosphere, their characteistics can serve as a good indicator of the atmospheric cleanness. Moreover, there is a big deal of equipment for real-time measuring of the aerosol particle size distributions.
The project will result in development of atmospheric gas-aerosol data bank for the background areas of the Baikal and Mondo regions.
The project will result in development of gas-aerosol data bank for the background regions of lake Baikal and Mondo, a complex numerical complex model for transport/transformation of the atmospheric pollutants characteristic to these regions. Since the measurements of aerosol size distributions will be performed simultaneously in distinct points, it is intended to perform a correlation analysis and comparison with numerical calculaton results. This will permit us to validate and improve the numerical model making it more comprehensive and appropriate to the specifics of the regions under consideration.
In mathematical modeling activities, a combined approach will be employed taking into account the local topography, heat- and mass-exchanges, kinetic processes of transformation (nucleation, condensation, coagulation), processes that proceed on aerosol surfaces, and heterogeneous ones.
The project participants have a rather great experience in studying a wide range of theoretical and practical problems in atmospheric processes and their modeling, which has been refleced in the following list of publications.

The project collaborators are highly-qualified scientists in the areas of atmospheric chemistry and physics as well as mathematical modeling. They will most successfully estimate a scientific level of the project and assist in conducting experimental campaigns and joint publications.
