Anomalous Dynamics of Tropospheric Ozone in the Spring of 2020 in Central Russia

Surface Ozone in the Atmosphere of Moscow during the COVID-19 Pandemic

“…A simultaneous compliance with the strict lockdown measures in many countries has led to a marked reduction of pollutant emissions to the atmosphere around the globe, which was recorded by many atmospheric air quality monitoring facilities [ 25 – 27 ]. It is noteworthy that the events with anomalous (both too high [ 33 , 34 ] and too low [ 35 – 37 ]) ozone levels in the surface atmosphere were also reported [ 28 – 32 ]. After strict lockdown measures were imposed, we, too, recorded the effect of SOC reduction at the surface ozone monitoring station, located in background plain region in Central Russia in Vyatskiye Polyany, Kirov oblast [ 37 , 38 ].…”

At this station in late March, i.e., just after the high-alert announcement in Russia, there was a jump-like three-fold reduction of SOC values, both monthly average nighttime minima and daytime maxima.…”

Data parallel processing in block streams for analysis of long-term series of ozone content in ground atmosphere

“…Long-term monitoring of atmospheric parameters including meteorological parameters and concentrations of gaseous chemical compounds plays an important role in modern research in atmospheric physics and chemistry [1][2][3][4][5][6][7][8][9]. In this case, data series over a year-long are recorded with high accuracy and a fairly good temporal resolution of the order of 1 min for each parameter under study.…”
