Ozone Content over the Russian Federation in the First Quarter of 2020

The review is based on the results of operation of the total ozone (TO) monitoring system in the CIS and Baltic countries that functions in the operational mode 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 functioning of the entire system is operationally controlled in CAO 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 first quarter of 2020 and for the first quarter. Data of routine observations of surface ozone values in different regions of the country are also presented.
