The review is compiled based on the results of operating the total ozone (TO) monitoring system functioning in operational mode at the Central Aerological Observatory and covering Russia and adjoining territories. The monitoring system uses the data from the national network equipped with M-124 filter ozonometers under the methodological supervision of the Main Geophysical Observatory. The quality of the entire system functioning is operationally controlled based on the OMI satellite equipment observations (NASA, USA). Basic TO observation data are generalized for each month of the third quarter of 2024 and for the third quarter as a whole. The data of routine observations on surface ozone in the Moscow region are also presented.
IVANOVA et al. (2025) studied this question.
