Abstract:

The paper presents some results of preliminary analysis of the spatial distribution and temporal variability of the CO concentration over continental Russia obtained from measurement data of TROICA experiments along the Trans-Siberian Railway from Moscow to Khabarovsk. It is shown that positive anomalies of the CO concentration in spring are mainly caused by the anthropogenic activity, while in summer they are connected with the biomass burning. The revealed features of the intra-annual variability of the CO concentration are in a good agreement with the observations at the background sites. The main feature of the spatial distribution of carbon monoxide over the continent is an increase of the concentration toward the east in summer and toward the west in spring.
