This article analyzes the results of measuring the oxygen content in Moscow in 2017–2021 at three Budgetary Environmental Protection Institution Mosecomonitoring automatic stations for monitoring atmospheric pollution. Seasonal variations in oxygen content in the city are considered, the issues of compliance of the values with the scale of comfort level for human breathing developed by medical specialists are discussed, and measurement data are compared with the results of calculating the oxygen concentration in the air by the magnitude of meteorological parameters. According to the measurements, diurnal variations of the O 2 content in the surface urban air, more pronounced in the warm season, are revealed for the first time. The minimum O 2 content is observed in summer in the early morning hours. The main natural and anthropogenic processes that determine the variability of oxygen content in the surface air of a megalopolis at different time scales are discussed.
