Study of Air Composition in Different Air Masses

Resumo

Data of multiyear monitoring at the TOR station are used to calculate the average concentrations of gas and aerosol constituents in different air masses in the region of Tomsk. It is shown that CO₂ and CH₄ are characterized by a decrease in concentrations in going from an Arctic to a tropical air mass. Ozone shows the opposite pattern: the largest concentrations are recorded in the tropical air mass and the smallest concentrations in the Arctic air mass. Such gases as CO and SO₂ show distributions more complex in character.
