Abstract

In this paper the results of the study of diurnal and annual behavior of concentrations CO₂ and CH₄ are presented. This study is based on monitoring data using gas concentration analyzers in the surface layer of the atmosphere in urban and background observation sites in the Middle Urals in 2021 – 2022. Two maxima and two minima in the annual behavior of CH₄ concentration are observed for urban area (maxima: December – January and August; minima: May-June and October- November). One maximum in January and one minimum in May and summer months in the annual behavior of CH₄ concentration are detected for background region. The annual variations of CO₂ are differing in two areas: the highest values were recorded in December to January for urban site and in July for background monitoring point. The diurnal variation CH₄ concentration is maximal in July and August in the urban area. The changes from minimal to maximal CH₄ concentration are ∼20% The highest diurnal variability of CO₂ is observed in July at the background area (∼47%).
