Abstract

In the work, a new technology of aircraft sounding of the atmosphere is described. In combination with modern software, it allows investigation of large-scale features of spatial distribution of air composition. By means of this technology large-scale spatial distributions of aerosol, CO, CO2, and O3 over the Arctic coast and the continental areas of Siberia are investigated. Cardinal distinctions in distribution of aerosol, CO, and CO2 over the continent and the coast are revealed. This is caused by distinction in the power of sources and sink of impurity in the areas considered.
