Abstract
The annual and diurnal variations and trends in the concentrations of CO (during 2013-2017) and CO2 and CH4 (2013-2018) in a suburb of Saint-Petersburg (Peterhof, 59.88 N, 29.83 E) are studied. The growth rate of CO2 concentrations is 2.43 ± 0.15 ppmv/year, of СН4, 8.7 ± 0.6 ppbv/year, and of CO, -3.3 ± 0.5 ppbv/year. The results are comparable with the gas concentration variations on the global scale.
