Abstract

In this study, we present statistical analysis of the main patterns of carbon dioxide, methane and carbon monoxide variability in the surface atmosphere of Ekaterinburg city in 2017-2018. Background levels, mean diurnal cycles, and the dependence of mole fractions on wind speed in different seasons were estimated. The measured mole fractions significantly exceeded the corresponding background levels during all seasons and both of these components had a pronounced seasonal cycle. The highest diurnal variability in urban environment was observed in summer and early autumn. Simultaneously registered meteorological conditions suggested the decisive part of local anthropogenic sources in such a dynamics of measured greenhouse gases.
