The review is compiled on the basis of the results of the operation of the total ozone (TO) monitoring in the CIS and Baltic countries functioning in the operational regime at the Central Aerological Observatory (CAO). The monitoring system uses the data from the national network with M-124 filter ozonometers under methodological supervision of the Main Geophysical Observatory. The quality of the functioning of the entire system is under operational control based on the observations obtained from the OMI satellite equipment (NASA, the United States). The basic TO observation data are generalized for each month of the fourth quarter of 2011, for the quarter, and for the year as a whole. The features of the development of the spring Arctic and Antarctic ozone anomalies in 2011 are described. The results of regular observations of surface ozone content in the Moscow region are also generalized.
