The main aim of the project is to investigate the changes of the tropospheric composition over Russian midlatitudes. The project is based on the long-term measurements of the greenhouse and associated gases across Russia in train-based experiments TROICA.
Unique equipment complex, extended route (of about 8500 km) across a continent and the period of campaign (since 1995 to nowadays) give a unique opportunity to investigate a complex interactions of key tropospheric species under different conditions, to understand mechanisms of their variability, to evaluate an impact of air transport and diffusion and to refine the budget of the carbon compounds over Russia.
An application of isotopic analysis is planned to be compared with a trajectory approach to improve and understanding of greenhouse and associated gases regime. Among the compound atmospheric methane, carbon monoxide, tropospheric ozone, nitrogen oxides, some VOCs and atmospheric aerosol will be studied.
These measurements will be critically compares with transport-photochemical models application (like, TM5, MATCH, SHIMERE and LOTOS) and they also will be used for validation of the global emissions database.
Contribution of anthropogenic and natural sources of greenhouse and associated gases and aerosols will be estimated. The role of the separate mechanism of variability will also be studied.
