Ozone Content over the Russian Federation in the Second Quarter of 2024

The review is based on the results of total ozone (TO) monitoring over the CIS and Baltic countries by the system functioning in operational mode at the Central Aerological Observatory (CAO). The monitoring system uses the data from the national network equipped with M-124 filter ozonometers that is under the methodological supervision of the Main Geophysical Observatory. The quality of the functioning of the entire system is operationally controlled at CAO by the comparison with the OMI satellite equipment observations (NASA, USA). Basic TO observation data are generalized for each month of the second quarter of 2024 and for the whole second quarter. The data of surface ozone routine observations in the Moscow region are also summarized.
