Ozone Content over the Russian Federation in 2017

The review is based on the operation results of the system for 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 data from the national network equipped with M-124 filter ozonometers being under the methodological supervision of the Main Geophysical Observatory. The quality of the entire system functioning is operationally controlled in CAO through the comparison with the observations obtained from the OMI satellite equipment (NASA, USA). Basic TO observation data are generalized for each month of the fourth quarter of 2017, for the whole fourth quarter, and for the whole year. The data of routine observations of surface ozone values in the Moscow region and Crimea are also considered.
