Ozone Content over the Russian Federation in the Second Quarter of 2019

The review is based on the results of the operation of the system of total ozone (TO) monitoring over Russia and neighboring territories that functions in the operational mode at the Ceniral 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 by the comparison with the observations obtained from the OMI satellite equipment (NASA, USA). Basic TO observation data are generalized for each month of the second quarter of 2019 and for the second quarter. Data of routine observations of surface ozone values in the Moscow region and Crimea are also considered.
