The monitoring system uses data from the national network of M-124 filter ozonometers being under the methodological supervision ofthe Main Geophysical Observatory. The functioning of the entire system is under operational control based on the observations obtained from the OMI satellite equipment (NASA, USA). Basic TO observation data are generalized for each month of the fourth quarter of 2015, for the fourth quarter, and for the year as a whole. The results of regul ar observations of surface ozone content carried out in the Moscow region and Crimea are also provided.
